back to article PC tune-up software: does it really work?

We love hardware, and if you ask us how to make an old computer go faster, we’ll recommend a hardware upgrade. But 34 million people opt for a software tune-up in the US alone, estimates Iolo, a company that makes tune-up software. PC speed-up software Iolo's System Mechanic 9 does a good job of finding services you don’t …

    Memory upgrade

    A memory upgrade is possibly the easiest thing for even a novice. And these days it's incredibly simple to get the right product for the system - Crucial supply a system scanner that tells you what system you've got, how many banks are free and what memory your machine can take (taking into account BIOS limits etc)

    A memory upgrade will also lower boot times as noted in the article. The result seems quite contradictory, but in layman's terms, when Windows boots, it will load as much as it deems appropriate into "real" memory, and load the rest into virtual memory/disk. It still goes through the same process to do this though, but can't write to virtual memory as quickly as the real thing. If you're in the habit of hibernating the system though, it will increase the resume time (but it's a fairly swift process to begin with)

    To be honest, I'd say that a non-tech person would have as much luck with an upgrade as they would with something like CCleaner

    Just for interest, and something you've not mentioned here. How much difference does a defrag make to the boot up times? Or is that subject of another article?

    I use Ccleaner just to tidy up after de-installs or upgrades (MS tuesdays seem to leave a lot of crap in the registry after you've rebooted). The Startup apps screen in Ccleaner at least allows you just to turn them off which does mean its pretty easy to turn them back on if you've screwed up.

    Regaining virginity ?

    Useful article, but what is disappointing is that none of the applications get start up time anywhere near the original 35secs of the new clean install - One feels something could be done to recover this? Is it just extraneous applications that slow down boot? If so, are they really needed? Or could they be arranged to splutter in to life when the PC is up and going rather than forcing the user to wait till they sort themelves out before allowing the user to do anything useful.

    Agree about the memory upgrade, particularly for really 'challenged' PCs e.g. 256Mb - its quite easy to do as well - just need to be careful and gentle.

    'Twas ever thus

    PC manufacturers have skimped on memory for at least as long as I can remember, which is 15-20 years now. It has always been the case that you'll get a faster machine by starting with the manufacturer's config, downgrading the processor, and spending the saved cash on extra memory.

    I assume it is because PCs are sold by the number that Intel/AMD assign to the processor, rather than the numbers that the resulting configuration scores in benchmarks. It's rather sad that the general public have been getting shafted for 20 years and *still* haven't noticed, to the extent that those who *are* disappointed with their PC's performance and are willing to spend more cash get diverted down the blind alley of "tune-up tools".

    yes, errr no, ... um - yes

    it's impossible to say.

    There's a huge placebo effect with stuff like this. partly because the average PC user cannot detect performance improvements (or drops) of less than 50%, so a tune-up on a decently working PC will be indistinguishable from nothing. Yes, it will just about twitch the needle on a benchmark, but for the average Joe: nada. --- Although they'll aways say it "feels" faster, just to be polite.

    But ..... the average PC that's been in use for a year or two is going to be in such a state that it's hard NOT to improve it's performance. The main drag seems to be all the temp files, garbage in caches and millions upon millions of cookies. Assuming of course, that there isn't one or more viruses or trojans lurking in there, somewhere.

    I just wish all the cr@p cleaners, tuner-uppers and the like would just stick to the basics: remove the junk, scan for baddies and then stop. There's no measurable speed benefit from defragging the registry, or removing orphans or any of these other features, that software makers feel compelled to add, just to bump the revision number to show they're still in business. Once you get past the basics, the chances of screwing things up badly and without noticing go up very fast. Especially for the sort or average users who need these utilities the most.

    Re: Memory upgrade


    From personal experience: 256MB-->512Mb moves you from arthritic, hod-carrying snail to three-legged dog in performance. 512Mb-->1Gb a stonking improvement all round. 1Gb-->2Gb little, if any, improvement to boot times, but a massive improvement to task switching, exiting Office apps / games et. al. and so on. 2Gb-->4Gb, very little change over 2Gb (and here remember only the 64-bit lads get to see it all anyway).

  18. SynnerCal

    Well I hope version 9 is better...

    ... than the v8 of System Mechanic that I suffered from. V7 was actually pretty good and seemed quite good at maintaining a reasonable level of performance from my old XP system.

    Then I got the 'special offer' to upgrade to the latest version, and it all went downhill from then:

    o The system started fine, but over time it seemed to get slower and slower - with long periods where it would freeze. 15 minutes between pressing the power button and getting a usable desktop is not my idea of "fun";

    o The Iolo software needed to do a software and system scan - and these seem to get more and more frequent and intrusive. The software updates seemed to increasingly need a reboot, and the scan times were up there with the AV ones;

    o Strange things started happening - like software apps would intermittently go 'lost' only to return minutes later. Wireless cards would be disabled;

    The final straw was following a 'major update' - it did a registry optimise and managed to corrupt the registry keys for a number of apps. E.g. trying to launch IE resulted in the system trying to start an install of Nuance PDF Creator.

    After doing some tests, I duly reported this to Iolo "support" and was treated with barely disguised contempt - effectively "we've got your money, ha ha sucker!".

    I removed their software (as in deinstall and then had a session with a registry editor to totally purge it) and lo-and-behold - my system freezes stopped, boot times reduced dramatically and the system was a lot more stable. Okay, I then had to spend hours trying to undo the damage it'd done to the registry (and no it didn't do a backup, and I didn't get a chance to fire off a manual one before it hit my system) but the system was fine after that. And yes, I did do a full virus scan, in case it was some nasty piece of malware to blame for my ills!

    So - while I realise that I may be just been really unlucky) - if you're going to use these (especially System Mechanic!) then make sure you've got good backups in place. Oh, and maybe learning how to do manual tuning (or use some less highly automated tuning tools) would also be a good idea.

    who give a F*ck. desktop or laptop - surely most folk make use of standby and hibernate ???

But this is not a 'macs are great' mail, my old XP laptop was quite happy hibernating daily too.

    Nice review, BUT....

    Did you disable the page file after you had given the laptop the full 1gb? If not, why not? XP only needs p/f with under 1gb of RAM, if you run your tests again with the p/f off and a quick blast of Microsoft's 'bootvis' and I bet you'd see yet further increase in performance, and these tweaks are well within the realm of the novice.

    Sometimes removing virtual ram altogether speeds up boot (especially reboot!) faster than spending a penny on anything! although it will limit memory available, it will speed up its use considerably.

    not sure if you guys are aware but CCleaner stood for Crap Cleaner, hence doesnt really tune-up speed wise but makes sure you can get rid of crap etc. Google for CCleaner space results or something similiar, some people shave 1-2Gb off their hard drives.

    Waste of time TBH

    I do a LOT of system optimisation, I'd say probobly 80% of my workload involves this. Theres a simple procedure to follow that will seepd up almost any machine and its been the same on all but a few systems.

    Disable and remove whatever Norton Product is running.

    Run Antimalware, anti virus. Normally by this stage the machines that were struggling are quite spritely again.

    Prune the startup through msconfig (yes you really need all those bloody updaters, quick starters, media detectors, print notifiers)

    Defrag if needed, then a few small tweeks here and there.

    It works on both XP and Vista just as well. There are a LOT of tweaks to be applied to Vista, simple things that make a huge difference.

    What you fail to mention is that a huge number of these system cleaners are bundled with, or in fact are themselves, malware. The next thing the user knows, Personal Antivirus is on there and it all goes pear shaped.

    A proper clean up of the machine and then if needed, RAM will do the trick every time. As will sorting out some of the manufacturer gaffes a lot of the big box machines ship with (no DMA, Chipset drivers missing, shadowing off, 40pin ide instead of 80 pin ATA...)

    Ccleaner (was Crap Cleaner) is great for popping in and seeing what has been bunged on start-up after installing things like camera, printer and Adobe stuff etc.

    Amazing how many progs feel the need to be ready to connect to the net and check once every half an hour for updates or have a toolbar or dashboard or other interface hidden but ready to go.

    A quick peek on Ccleaner and a few 'what the f's that?' works wonders.

    interesting article

    I must admit I pretty much guessed the results fairly accurately at the beginning of the article, but it's nice to see someone actually put in the legwork and do some serious testing.

    When one of my users complains of performance issues the first thing I do is look at how much RAM they have in their system, but immediately afterwards, I clean the startup list and defrag the hard disk. Defragging can have truly dramatic results. Also, upgrading to a faster hard drive (more cache, lower seek times) can do wonders.

    The biggest job out of these is actually defragging, as it is the most time consuming. Requiring manual initiation, often requiring many passes, and frequently needing some space freeing up to get the job done properly.

    Because of this, it is infrequently done in XP, which exacerbates the problem. (as I write this I am currently remoted into 3 separate desktops running updates and defrags after migrating them to a new domain) This is entirely because of politics, as previous versions of windows could indeed have defrag scheduled automatically.

    MS bought the defrag technology from Executive Software, from their flagship product Diskeeper. Because of this, Executive Software retained the rights to core components such as the scheduling agent, and the boot-time defrag which could process normally locked system files such as the pagefile and the registry files.

    Thankfully, this has changed post-Vista. Not only can defrag be scheduled again, but the windows scheduling agent has been given a steroid injection (seriously, if you've got a vista or 7 machine knocking around, and you've not seen it yet, have a look in computer management, it's very powerful).

    Of course, from a sysadmins point of view, the scheduling can all be governed from group policy management on the server, so you can dictate whether your domain machines perform a defrag at a given time, or on a given trigger, such as the computer becoming idle.

    I'm not saying this is THE critical update that we've all been waiting for, but any sysadmin will tell you, after a couple of years of neglect, that hard drive becomes fragged to the point where a reinstall can require fewer man hours.

    however, it correctly diagnosed an old HP pavilion i had to only be able to take 512Mb sticks, as it wouldn't post with the 1Gb's i had in for a Dell... even after a bios upgrade. anyway...

    It's not either/or

    You don't have to choose between stopping some services on start-up or living with slow boot times.

So my comp does a fast boot, and things like windows update are phased in five min later. During this time there's a little bar at the top of my screen which tells me the loading state of the programmes I've delayed.

    First off, good article -- it's nice to test the claims of these cleaners, and see which actually do the best job (however little it is, compared to having a clean system.)

    I'm surprised none of them really shrunk the registry down. This seems "questionable", but really is possible -- the way the registry is, no-longer-used keys will just be marked as unused, but that space is only reused if another key can fit in that space -- otherwise they registry grows bigger. It really can be defragged.

    It's very odd (ahh the mysteries of Windows...) that adding RAM changed the registry size, and I had to laugh that one of the products actually made it bigger 8-)

    Anyway... this all makes me happy I'm not running Windows. 80 seconds for Office? Bloody hell. My Ubuntu desktop here at work is a P4-2.4 with 512MB, and it starts openoffice in 14 seconds, off a rather slow 40GB disk. (And 4 or 5 seconds if I quit and restart, since it's then already cached.) I've tested a variety of systems (after all I work at a computer surplus), it takes something like a P2 with 192MB of RAM to get openoffice up towards the 1 minute mark (bump the ram to 256MB and it's down to roughly 20 seconds even on the P2.) And Openoffice is the slowest app to start I have, although Eclipse was pretty slow to start too when I was playing with it.

    @Andy 70, re: price of RAM

    Round these parts (downtown Bangkok) there are some very well-known (nay, notorious) IT emporiums that sell just about every kind of hardware imaginable (apart from the very latest or top-of-the-line kit, unfortunately). I noticed a few years ago that many of the shops had hoards of "old stuff" like P3 and P4 CPUs (not the recent ones), as well as SD-RAM and DDR1. Five years ago the prices were pretty reasonable, but recently I have seen that the prices of the old stuff has rocketed.

    I guess they offset the ever-reducing margins on the new stuff by keeping their stocks of the old kit and raising the prices as the demand keeps ahead of an ever-shrinking supply. If you really need it, then you really need it! And it's still usually cheaper to buy a couple of sticks of overpriced RAM than to replace a computer.

    To get ON topic, if your machine is running slow then buy more RAM. You are never going to need less in the future, and it's cheap enough right now.

    As for the software being reviewed, I never saw the point. A few simple steps (mostly outlined above) will save you some cash and time.

    Registry results incorrectly measured

    I just had a look at the KB page for dureg.exe and it says:

    "Dureg.exe measures data; it does not measure space. Note that because the space that data occupies varies with the storage method and the amount of free disk space that is available, the size of data and the amount of disk space that is used are not equal. Additionally, because Dureg.exe measures data, it does not account for fragmented-unused space in the registry."

    but is this what your readers are clamouring for? Don't we already do this stuff anyhow? Add memory, defrag the HD and remove unnecessary processes and files in startup, don't load unnecessary services, yada yada, comparing half a dozen products I would never buy in a million years. I'm not saying it wasn't interesting, though....

    what? no sysinternals references

    All these comments and not one reference to the sysinternals tools - pagedefrag, autoruns

    You can also see Mark Russinovich blog about why windows actually needs the pagefile even if you have enough ram.

    I've found

    That Windows Startup Inspector ( is quite handy.

    Use it with spybot resident, turn off all the unrequired services, get a hardware firewall, switch off auto updates & block MS in the hosts. Job jobbed.

    My XP PC is 2003 vintage with 512Mb of RAM & it boots in a tenth of the time the year old 4 core, multigig, Fista PC does at work & is more responsive :-)

    PS I added an old 4Gb drive, which is the swap.

    Keep a sense of perspective...

    In the free RAM plot (page 4) you're showing a range of improvement of up to 20MB in 300MB. It's going to be a rare edge-case for which this makes any real-world practical difference.

    Worse, the variation in registry sizes (page 5) you show is 170kB in 47MB, barely over 1 part in 300 (0.36%). Which I can't believe will make a blind bit of difference.

    Now, for comparison, show us the performance of the original system before you'd disabled anti-virus. Depending on your AV, I wouldn't be surprised if that used 100MB+ of RAM, increased boot-times by 30% or more, slowed Windows Explorer browsing of directories with 1000's of small files by a factor or 2 or 3... I'm not suggesting Joe average shouldn't use AV, but using a resource-light product makes a far bigger difference than any of the "tune-up" software you've looked at.

    Disabling Window's Fast Find or whatever they call their disk-indexing service is normally one of the first things I do with a new system - which makes things more spritely and gives the poor hard disk a break.

    Sorry, I thought this was a website for IT people

    "So, where do all these results leave us? The biggest game-changer in system performance was how many services and applications were enabled at start-up."


    This article read like something from the Evening Herald PC Corner, or gods help us, Ask Jack.

    Does anyone think the resource hits are down to anything except services and applications running at startup? Does anyone ever look at Task Manager, check what's eating their machine and pare them back? Hasn't anybody heard of msconfig? I've got Vista running here on a 2 year old laptop at about 2% CPU and using about 300MB RAM of the 1GB installed.

    I spit on your 'tune-up' software!

    Yep this was my experience with the Iolo tools too. My system has never fully recovered.

    Abuse of charts

    The Counter-Strike FPS and registry size charts should start at 0, like all the others. This display dramatically overstates the difference between various tests. The registry size changes are miniscule, and Fix-it Utilities doesn't cut the frame rate by more than half.

    @AC 19:43

    Yes, we techies do this already. But it's good to have a quantifiable measure of how much difference each of them makes. The comparison of the effectiveness of some products is also useful.

    In CCleaner's defence, it's a nice, free piece of software for clearing out temp files and trashing redundant registry entries without you having to fish around yourself. I wouldn't say it was for "speeding up" a system, simply to clear out some shite.

  67. Shaun Hunter

    BS benchmark!

    It is a fair comparison to leave these features/services turned off because the program's you reviewed were meant to do this. To alter how a program works during a benchmark of it is a farce. Especially when you conclude said programs don't live up to their claims!

    To gain performance through you have to lighten the load on the system. Did you think they included a magic version of the windows kernel and linking libraries? How you conducted the review negated their chance at being effective.

    I really expect better from supposed experts!

    Thumb Up

    I agree with techmind - AV's a primary cause of "slowness"

    So having tested changes to performance caused by 1) more ram, and 2) performance enhancing s/w, it would be godd if Emil could perform the same type of test but changing only the type of AV software each time.

    I often read anecdotal evidence of which AV product's the most resource hungry (and most people, including myself, wouldn't miss a chance to bash symantec for their bloatware) but i cant remember seeing a line up of AV products running on a slightly dated PC reviewed for performance.

    FWIW my favourite free AV (for performance) is Avira. And the worst I've ever seen (not free) was F Secure (I think that was what it was called - it was truely dire). But I couldn't say with any certainty if these are the best, or worst in their class. Nor could I say what falls in between and how they compare.

    Footnote: IMO the type of AV software a user chooses is the main cause of a PC running slower and slower over time - especially as each new version takes more ram, more CPU, etc.

    stating the bleedin' obvious

    Whilst in the employ of a rather good, and now sadly defunct PC manufacturer with a consumer line flogged through DSG, we were asked by DSG to test a raft of these applications back in the Windows 95/98 days. Without exception they were of dubious benefit, largely because without exception they all installed memory resident programs and insisted in firing stuff up at inappropriate times. This is commented on by Inachu and others.

    Not one of these products have any advantage over a bit of manual dicking around and regulalry purging the accumulated crap from months of web browsing (assuming you don't prevent the crap accumulating in the first place)..... Unless of course you lack the tech skills to make the right decisions - and that's the market these products are aimed at. Unfortunately these are essentially doing the self same thing, so it's no surprise that now and again PC's become unbootable..... They really shouldn't be used by those who lack the knowlege to make sense of what the tools are telling the user, which kind of negates their reason for being.

    If what your seeing as a user doesn't make sense, you shouldn't even be thinking about fiddling with it and should think twice about letting third party apps do likewise.

    Norton ? My wifes last two laptops came with free time limited Norton subs - the real price was abject lack of performance on the config shipped by the manufacturer (yeah even with 2 gigs of RAM). To be fair, the insane software preinstalls shipped by manufacturers caused me more grief supporting a local charity, family and friends than I would have ever considered credible and Norton was a major contributor to the problems they had with new kit.

    A word to manufacturers - I know commercial pressures and the marketing department all have input, but please.... please no more crippled pre installs on low spec lappies especially where you have half a dozen messaging apps, three or four "critical update" apps for drivers and preinstalled third party guff (critical my arse, just switch on Windows update and leave it, for the love of god) plus Windows/MS update on as default, Norton in the background, two third party LAN/WLAN management apps and god knows whatever else crapware running in the background. I've dealt with kit supplied by one big name that took twenty fsck*ing minutes to boot with software configured as supplied thanks to all the crap layered onto the preinstall.

    Finally......Getting rid of the pagefile ? errrr...... you're surely not serious. Fail.

  71. Dave H 2

    Agree with clean-installing...

    I've also dispensed with some "protection" - I stopped using Spybot S&D, particularly because it's "TeaTimer" component was getting so sluggish to load into the system tray (slow on my dual core/2GB machine, unbearable on my old lappy). I've also dropped AVG, in favor of MS's new Security Essentials. Will see how that goes, but truth be told no security app has warned me of anything useful in 5 years. Malware inflicted on my system (by family members) always required more "specialist" tools to get rid of. Family members have now also been gotton rid of (to their own machines, of course). :-)

    So now I'm just using Windows Defender & MSSE. I'd also like to give a nod to "Macrium Reflect Free Edition". I used it recently to move my OS to a new drive - I didn't want to re-install due to time and because the current install was only a month old, so XP Activation would have given me grief. Worked a treat. I actually look forward to finding the time to make a clean install, just so I can image it.

    Memory all the way

    Back when Windows 95 was first released most computers came with 4mb ram. I built myself a Pentium (120 Mhz) and kitted it with 64mb ram. It ran (at the time) like a dream.

    I kept it until 2000 and gave it to my parents who continued using it until 2003 when they bought a digital camera and it didn't have a USB port to connec to.

    The number of times people have said to me "oh my computer is running like a dog and the guy at <insert rip-off computer store name of you choice here> says I need to spend £'000s on a new one". I've usually made the computer last another 2-3 years by spending little more (and sometimes less) than £50

    My first PC was an IBM XT ; and it wasn't even my first computer. Since forever, I've seen snake oil sellers come and go, and some even making a profitable business (McAffee, Norton, etc.). Truth has always been Microsoft OS of the moment requires to operate normally (ie, not just running the system but working with it) at least twice the ram usually sold with the computer (and half the CPU speed, but you don't look a given horse's teeth). This rule of thumb applies to linux too, but you can get away with less by tweaking around.

    The main difference is a linux box won't degrade over time as much as a windows box will. Being conservative, I ran the same box from 2001 to this year, 900 MHz cpu - 512 Mb ram. This was a bit of a stretch, if you ask me, but it cope nicely with linux improvements nonetheless, until the video requirements for newer aero-like effects couldn't be met by upgrading my video card any more (they don't make fancy GPUs in AGP...). So I changed, loaded up the new box with 4 Gb ram, and chose an AMD 64x2 3800+ for CPU (this is a 2007 typical config, I erred on the cheap side). Runs great, but what's better, won't degrade in the foreseeable future.

    Meanwhile, windows users are still stuck back in time, standing where I was in the mid-90's, hoping a miraculous software will help them curing a defective OS running on a badly balanced computer. I don't even feel amused. I'm just sorry so much people keep on losing their valuable time and being ripped of their cash, waiting endlessly for a never ready computer. Pretty much a picture of Sisyphus rolling his boulder forever.

    Cruicially It's a bit wrong

    Sorry but I have to inject at the comment regarding the crucial post by Annihilator. You, sir assume that their scan software works correctly 100% of the time. I can assure you it does not.

    I used the scanner to see if I would be able to upgrade my RAM. I currently have 2 x 1Gb installed).

    Crucial's scanner informed me that I currently have 16Gb installed and would be able to increase that to 2048Gb. Yes folks I could have 2 TB of RAM!

    Always do the RAM first

    We finally got around to upping the RAM in a small suite of 8 public-access XP P4s dating from 2004, which shipped with a single chunk of 256MB DDR2 each. We took all the single sticks from the eight and amalgamated these into two, then invested £200 in 12*512MB and put these in pairs in the other 6. Result: 8 PCs with 1GB, hugely better performance (the extra capacity PLUS proper DDR pairing), boot times a small fraction of what they were before, actual multi-tasking and happy punters, all at less cost than a single replacement base unit. Our usual hardware supplier had, of course, suggested the best solution was 8 new PCs for a mere £2500 and relegating the old ones to landfill...

    Most of you sound like amateur technicians. Here's a better idea:

    Don't fuck your machine up in the first place. Make sure your e-mail client reads plain text, don't run any attachments, make sure your system is behind a stateful firewall, only access sites you trust with Javascript on, disable it for the rest. Don't run any untrusted downloads. Don't install crap on your PC you don't need, only install the software you explicitly need.

    Do all this and you wont need any kind of "tune-up", you wont need AV software slowing your machine down. Even if you're mentally incapable of trusting yourself not to run dodgy executable binaries you can at least install AV but no real time protection and make it run a weekly scan or similar, but a competent technician would know as soon as an executable has done something dodgy to their system and could manually mangle it out of the registry with no ill effect anyway.

    If your friends and family are the problem let them have their own system(s) isolated from your network by a VLAN if necessary with heavily firewalled outgoing access and no incoming access. If they get malware slowing down their system leave it on, the slower their system the less harm they can cause everyone else with their idiocy, if you speed their PC up it'll only mean they'll be able to hand their life savings over to Prince Imascammer in Nigeria faster anyway.

    It's just natural selection, those who are weak get ill with malware and are slowed down and eventually die off of the internet when something whipes their PC, whilst those who are strong don't get sick with malware and can continue to do what they do at full speed, spreading their knowledge to eager to listen intelligent people amongst the younger generation. A good firewall config will prevent their infected PC making any dangerous outbound connections.

    May this post of advice allow some of you amateurs to grow and become the strong, those unencumbered with pointless things like AV software. The rest of you can simply continue on your path to become victims of Mr Imascammer and co.

    @Kanhef Re: Abuse of charts

    Hear hear! Truncation of graphs is a statistical evil we can live without.

    There's the FPS graph, where a 2% difference winds up looking like a 50% difference, and the registry size, where 150 bytes out of 49000 or so (0.3% change!) *also* looks like a 50% difference. A 2% change in framerate is statistically significant, but I challenge anyone to notice it by eye. The changes are displayed entirely disproportionately.

    @AC 12:18 GMT: Some of us deal with systems used by people who, y'know, actually WORK for a living, and pay our princely salaries in part to keep them working efficiently. Some of those people are stunningly ignorant outside of their areas of expertise and can be relied upon to open every piece of junk that hits their mailbox.

    As such, antivirus and other protection measures have their place, and system cleanup is an ocasional necessity, although we find the best way to do this is to keep work files on a network drive and reimage each PC from a fresh image when it gets screwed up.

    I was interested to see that the system tuners pretty much matched my expectations, i.e. they were all fundamentally useless. Defrag regularly and keep your startup clean (HijackThis! does a decent job and is free, but requires a clue to use) and you'll do as well as most of the packages reviewed here.

    Odd that nobody else has mentioned browser objects here, which HijackThis! can also clean up.

    I have heard that as AV scanners go NOD32 is superior; effective with a small CPU & memory footprint. Not having used it myself, this is merely rumour to me at this time. I can state that the system overheads from Mcafee are ridiculous - resident memory usage frequently exceeds 150MB even when idle and CPU exceed 50% when actively scanning.

  78. mariushm

    Defragment the drive already

    You'd probably achieve the same effect as TuneUp Utilities by simply using a smart drive defragmenter like o&o defrag to move all executable and frequently accessed libraries (dll files) to the front of the drive.

    Setting the swap file to a FIXED reasonable size (and then using the drive defrag software to move it towards the front of the drive) also helps a lot.

    Here here for NOD32, uses about 45MB of memory, which is quite little compared to other antivirus products.

    Nobody needs these tools, defrag is total waste of time. putting swap at the end of drive is total waste of time, makes absolutely no sense at all, BTW. Then again, Windows mem management makes no sense, either ...

    What a performance increase do you get by deleting 15 unused registry keys If they are not in the following three locations?

    HKLM/Software/Microsoft/Windows/Current Version/Run

    HKCU/Software/Microsoft/Windows/Current Version/Run


    HKLM/Services/Current Control Set

    Nothing, forget about it ... Those are the only places where you should delete stuff and these tools come up with registry keys nobody, not even Windows cares about ... ok, they "clog" up the registry, but you do need quite a few to clog up a registry, never happened to me ... ;-)

    Read a book about MS Windows, pay special attention when it comes to startup section!!!

    Check google for msconfig.exe (which you can copy to win2k, together with another file to have it work there, too).

    On startup tab, take note of what looks suspicious ... nobody wants office/acrobat/blabla to start when Windows starts (All except AV, I say).

    A few myths still floating around amongst the tech literate...

    Disabling the page file can be done simply, safely and is worthwhile for many people. I've read Russonovic and he's wrong, it'd be tedious to go into explicit detail of why but basically he incorrectly analyses the information, rather than being incorrect about the overall technical detail (which is his real field of expertise, in fairness). In practice, most users with enough memory to be disabling the pagefile (it doesn't actually disable paging, by the way), which is just about any system made this century and many older, should probably just set a fixed and very small one, in order to avoid problems with some software that blindly checks for it instead of trusting the OS to do its job as configured by the admin. The specific gain is hugely increased response time, especially from applications you have minimized or where the machine was left idle for any significant period, as well better caching (it's now always in RAM and not occasionally paged out to HDD). The danger is that you manage to put together a working set which really does exceed your available memory and applications begin to get failure responses when making allocation requests. I've never seen this happen without actually deliberately coding it, for test purposes (but I run with 4 GB on my systems).

    That brings us to the next myth... Windows XP, yes even 32 bit XP, can see 4 or more GB just fine. In fact it can see whatever physical memory is installed as long your BIOS can see it properly, you do NOT need a 64 bit OS to take advantage of a lot of memory but a 64 bit OS will make more efficient use of it in many ways (at the cost of some significant overhead, but you have a lot of RAM now, right?). The limitation is the number of unique addresses possible and Windows lies about actual address anyway (to put it simply) so that applications can be writing to the same location (if you believe the raw address) but are in fact not. There is also the 2 GB limit on continuous addressable memory, PER APPLICATION, which can be increased to as much as 3 GB with a boot switch (but there are side effects) and can be circumvented cleverly anyway.

    Truly, if you guys are what passes for the tech elite or even the tech monkeys, these days it is no wonder products like these sell to your customers and friends.
