back to article Windows XP activation algorithm cracked, keygen now works on Linux

Over 21 years after it first came out, the Microsoft operating system that will not die is receiving another lease of life. It's possible to activate new Windows XP installations, safely and securely, without a crack, offline. A blog post on tinyapps has revealed the hot news that nobody sane has been waiting for: the …

    DO NOT go on the Internet with XP

    Just don't do it. Forget "don't go to dodgy sites": don't connect AT ALL. There are vulnerabilities in the TCP/IP stack and you are a sitting duck waiting to be attacked. You don't even have to proactively connect to anything to get attacked. If you're very lucky, your router firewall might save you, but it might not.

    If you must run XP to run some ancient piece of software you can't emulate, fine, but do not connect that box to the Internet, ever. If it's a VM, share files with it but don't give it Internet access.

            Velveeta is not cheese. It is something called ‘cheese food’. Hint: both words have nothing to do with the abomination that is Velveeta. Velveeta is the real reason why a certain Orange-u-tan is the color he is, and even he has sufficient sense to only apply it externally, and to never, ever, ingest the stuff. Velveeta is evil. Velveeta should be banned by the Geneva Convention. Even Pony Boy Putin won’t use Velveeta offensively; he will threaten to have the troops eat some if they won’t attack.

              It's perfectly capable of sending on some network traffic as a proxy, DDOS bot, or C&C link. It's likely terrible for cryptomining and may not have access to sensitive data. If it's part of something important, it could be a great thing to attack with ransomware because, if it's not firewalled off, it indicates the user probably isn't backing up anything.

              Probably some types of criminal would turn their nose up at it, but there are still some cases where it's worth attacking.

            But nobody does that anymore, unless it's some bizarre willy-beating exercise. You connect "to the internet" through a router NAT device and a "firewall" application that is allows you to punch holes through the NAT. You can sit behind that forever, or at least until the router is compromised.

          I have a customer we've kept on Windows 7 32 bit because they have a DOS program that interfaced to old hardware on the serial port.

          Windows 7 32 bit was the best I could do upgrading from XP.

          I recently regraded them to Windows 10 64 bit and discovered DOSBOX could run the program and interface to the serial port.

          I expect that it's not Windows programs keeping people on XP but DOS programs. Windows programs will generally work on newer versions of the OS.

          However I await the arrival of WINE for Windows so it can run old Windows programs natively.

            32 bit applications like Office 97 require the 32-bit ODBC framework. That's fairly easy to install.

            The only problem I've had is with MAPI. MS never bothered to provide a generic COM 64:32 interface, or a 64 bit proxy for the 32 bit MAPI COM object, so 64 bit applications are unable to use Outlook97.

      I have a customer that still uses XP, a jewelry store. The old guy wrote his own inventory and accounting systems in basic and XP is the last OS where printing works in his old DOS program. The computer isn't networked at all, it's connected to a parallel port printer, that's it.

      If anything happened to his computer we'd be installing XP on an old junker or something. In which case I'd keep this hack in mind.

      1. WolfFan

        My mother has been going to the same optometrist for nearly 30 years. All billing and payment is handled by an ancient DOS application running on an XP machine. He still has two spare machines sitting in a back room; periodically, someone (guess who) gets to take them out and test them to be sure that they still work. The system does not connect to the Internet. The system does not even know what a credit card is. (Seriously. You pay by check or cash or, in our case, by keeping the computer alive. And none of that pay by phone nonsense, either.)

        The DOS app, and the XP machine, will be retired when the optometrist is. Dinosaurs live forever, so that ain’t happening soon.

        I shall be investing in a few copies of the items in the article, so that I can revive a dead XP box if necessary. The optometrist has all the install disks (actual 5.25” floppies, backed up to 3.5”, and then, by me, to CD) and license keys and what not, in the back room next to the spares. You would not believe what a complete set of WinXP and Office 2003 floppies looks like. I didn’t even know that you could get Office 2003 on floppy… (Yes, the floppy drives, one each 5.25” and 3.5”, still work. The hard drive is a massive 100 MB, 3600 RPM Western Digital thing which I think is still running only due to magic pixie dust.)

          I didn't even know you could get *XP* on floppy....!

          According to this StackExchange thread it came on 250 discs. I suppose there must be a few niche cases where someone might want XP on a machine which didn't support installation from CD- that customer obviously did- but they must be very few.

          (And with 250 discs, the risk that even one was bad- and the time you'd have wasted swapping them out- would be high enough that you'd want at least two sets.)

          I can only hope that if the optometrist's machine *does* need reinstalled it can be done from CD, because there's no way in hell that many floppies are all going to be intact after all that time.

          It's interesting living history. There is no business case to upgrade unless they intend to upgrade their business practice too. If they took electronic payments then it would pay to have that integrated into the same system but honestly a stand alone card system payment could be entered manually.

          A great deal of what we do as a computer industry is to obsolete working systems and replace them with something we claim is better. We know it's better because 32GB is better than 8GB but then that's only true because we did something that makes 8GB not as capable as it was when it arrived. Now we have 32GB we're at liberty to make any 8GB system unable to keep up. Perhaps not 8GB obsolete yet but 2GB is.

            > now we have 32GB we're at liberty to make any 8GB system unable to keep up.

            True. I noticed it at work yesterday, and I work in IT. The 8 GB Laptop is with AV, Teams, Outlook, Browser and Citrix at 80% RAM load, after a little while close to 90%. Note how I complain about the programs (marketing speech APPS). I forgot about it and wanted to test something in a virtual machine. Had to give it up after I looked in the task manager. I used one of those left-over ~9 years old Hyper-V clusters which are still running, even though 95% of VMs have been migrated away. Which, in hindsight, I should have done in first place.

            As for Windows 10 itself: 4 GB RAM is enough, it just depends on the applications you run. But don't try with less than 4 GB, neither OS or current applications work well with hacks. Better use Server 2022 for machines with 2 GB RAM or older/other OS.

              You definitely get a beer from me. At my previous employer one of my daily drivers was a machine running XP, and having an Acronis image of it on an external USB HDD saved me on at least three occasions. Having the image, along with an archive of all critical files/documents/scripts/etc. dumped on there monthly via a robocopy script meant I could be back up and running in less than an hour.

              1. Chloe Cresswell Silver badge

                I really wouldn't want to make an image of a 60GB drive, with 25Gb of data, over usb 1.1 Which is all this machine has.

                That's why we have backups. Reinstall windows, restore backup, activate windows, machine back in production.

                1. doublelayer Silver badge

                  The USB path wouldn't be fast, but it would take several hours (ideally about 4.5, but I'm willing to double that). That could be completed overnight. I wonder whether installing and activating Windows by phone is really a shorter process. Also, if you want to go faster, does that machine have an ethernet connection? That is probably faster.

                  1. Chloe Cresswell Silver badge

                    Installing XP took an hour. XP working gives 100mbps ethernet, the backup is 8.25Gb compressed, and restores in about an hour. Activating takes 5 mins. Machine was back in operation before the end of the day.

                    Plus, even if you imaged it via ethernet, you'd still hitting the issue of finding a replacement 2.5inch PATA drive that the system can use. Anything over 100GB won't be recognised. Most imaging software I have access too won't image onto a drive smaller then the original.

                  For slow systems using an external IDE/SATA drive connected to a motherboard connector, provides a much quicker duplication of a hard drive.

                  1. phuzz Silver badge

                    Or for that matter, I guess PATA disk duplicators are probably pretty cheap if you can find them. Of course, you still need to find enough IDE drives which are still good enough to use as replacements. Hmmm, PATA->SATA adaptors maybe, or you can go PATA>CompactFlash

                    1. Chloe Cresswell Silver badge

                      PATA to SATA won't fit on the drive sled. There's only 5mm of movement for the drive between the connector and the drive due to the mounting slots. I'm currently running it from a 2.5inch to SD card converted which is cable tied to the sled, and if you put the cable ties on the wrong way, it won't fit into the slot. the metal plate in the middle of shot is the actual drive sled.

                  2. Chloe Cresswell Silver badge

           Want to put a 2nd HD in here? The metal plate is the drive sled. This is the IDE connector. This is the only IDE connector, the motherboard's circuity is wired to that PCI style connector. And you still need a HD to image too that the machine can use. anything over 100GB won't be recognised. Well, I lie. it will be recognised, as 30GB. To duplicate it, you need a 60 to 100GB HD. The last of which will be over 15 years old now.

            Fail to plan ahead = plan to fail

            The time to image the drive is when the data it holds would take longer to recreate from scratch than by restoring the image to a new drive, not after it has blown. Amazing this has to be pointed out

              We have backups. Imaging I find to be a pain when the machine only has USB1.1, and getting a replacement drive of the right size is an issue.

              Easier to install XP, and restore the backup, which doesn't care if the new drive is smaller then the old one.

                      What I must ask is how a machine could leave three drives borked consecutively - shoddy PSU perhaps barely capable of safely powering the system as sold? or the staggering luck of receiving three drives in that special category of 'not DOA but will be dead within the month'?

                      *Credit where due: I have a 'generic' 500 GB drive that's over a decade old and still fully functioning, which may not be unheard of bit remains a source of baffled wonder to me.

      There is no such thing as a truly secure O/S. You should consider any O/S insecure, even Linux.

      While I agree with you that Microsoft's treadmill of updates and upgrades only introduces more vulnerabilities. I disagree that Windows 11 is any less secure than any other version of Windows, all Windows versions have had their share of vulnerabilities. Granted Microsoft is years late in starting to secure Windows and it is inherently insecure by it's design, hardening Windows is a must now days. If you think installing Linux and running it in it's out of the box configuration is secure, then consider that there are hacking groups that only target Linux machines. As users and admins commonly run Linux in it's out of the box configuration without hardening or adding security.

          All operating systems have undiscovered flaws. This is why you use a zero trust model and secure everything you can. Where Linux scores is that it has a more secure configuration by default, but you should still take action to secure it further. even then, do not believe that it is invulnerable.

          The Windows configuration can be significantly tightened. A good place to start is the Essential 8 published by ACSC. Implementing as much of this as possible will dramatically improve your security posture, even on Windows.

      The challenge I found, and this was a few years ago, was finding hardware which plays nicely with XP and its drivers, having to remember whatever needs to be done to make modern PCs work with XP. I can only imagine it's got harder.

      When my XP system finally gave up the ghost last year I simply moved my chair sideways, continued with a Windows 10 system which was already set-up.

    OEM royalty SLP activation has been a work around for activating XP inside a VM for a long while. The XP VM i have on my laptop is activated exactly using this method.

    The XP installer basically looks for certain certificates in the BIOS which says it was a OEM installation. And you can add those into your VM config files and then Windows believes it was being installed on a real Dell, Lenovo, HP or whichever code you input.

    You do need to install from an OEM ISO (the ones that shipped with their PCs) for it to work, it won't work with VLM or retail copies, although I believe there are way of copying the install files from one of those and making a new ISO file which can work.

    That method would also work on most PC if you used a util to add a HP cert to the BIOS it would then activate using a HP XP reinstall CD.

    There is a discussion on this website from 2013 about using this method so its definitely something thats worked for 10 years +

    Oh and it also works for Vista and Windows 7 using a similar method.

    1. Roland6 Silver badge

      There was a website that had the OEM additions, so you could take any OEM install CD and convert it to another OEM. I used this to reinstall, a bunch of HP desktops using a Dell OEM CD. Obviously, the fun and games is sourcing the stuff that was on the OEM drivers disk…

    2. carl0s

      Yea and that's also how Daz's loader works on physical machines - it patches the firmware at runtime from the bootloader to have the SLP ACPI tables.

      Also has been possible to re-instate those tables on Dells that were bought without an OS via the asset.exe /PW:1234 tool.

      I do think it's a great achievement that somebody is generating confirmation codes though. Wonder if the tool is compatible with Office ? I had to call up for an Office 2019 activation the other month after reinstalling someone's computer, and the phone lines weren't working and nor were the dodgy websites that link to some MS API. After half an hour of trying, one of the phone numbers started working again.

    Since the actual hardware was run by an ancient sun hardware machine, the *scans* are marshalled by an ancient winxp box. Dead hardware.

    Overall *replacement* of the xray system would be in the 7 figure range.

    Brand new system, 2 vms. Two addon cards for the connectors, (Serial and Centronix). Spend 2 days getting the pass-throughs set-up to the vms and boom. Cost? less than 4K

    Yes, both talk to the interwebs, but the base install of linux firewall is (block everything) and whitelist things they have to talk to, and the inbound/outbound connection upstream is a proxy host, that has even more fire-walling and limitations.

    The images for the OSes are backed up weekly. The data never lives in the vms, its pushed up to a central repository.

    Too late the hero

    Don't ever connect?

    I discovered at least one XP machine in the extended family running last week. To date, it hasn't been compromised by anything, or at least anything immediately apparent.

    It may well be a lovely node on a botnet, but no ransomware encryption nasties have infected it, and the operators have not had entire lifesavings sucked out their banks, or online accounts hijacked.

    Bizarre, but true. You'll be asking "May be part of a botnet? Don't you know - haven't you nuked it from orbit!?" Well, I haven't bothered to look at it any further than a brief perusal out of morbid curiosity. A day, or a week is going to make not a blind bit of difference at this juncture, whether I take it out the back and shoot it, or not - besides I'm meant to be retired from all that nonsense.

    Security is hard, and you'll never patch all the holes in anything. My time in IT gave me PTSD, and the understanding that the advice is: 'never connect anything to the internet' - never mind WinXP. It's naive to think 'Hey I'm all patched up today - no vulns for me"

    Hell, even an airgapped machine will get royally screwed the minute a grunt gets a hold of it - there is absolutely, unequivocally, zero defence against stupidity.

    Best you can ever do is have backups, and go home for a pint. Some survive the battle for a while, in the same way a dandelion survives the mower - dumb chance. You can swerve around all you want, heroically running from the treeline every day, if you feel it helps. 'He killed 15 zero-days single handed...30, if you like'

    Yeah, that XP machine has to die, of course it does, though some twisted part of me wants to leave it operational, and to snoop the bejeezus out it, just to see what myriad nasties are operating in there - and if there are none - how in the seven hells there aren't.

      Your domestic XP machine, if behind a standard NAT router/firewall is only really vulnerable when it has an active internet connection. So if all you use it for is reading El reg and the BBC say, the likelihood of catching any malware is very low.

      Interestingly, recently been using a Windows system that has Avast installed, along with the Avast “secure” browser which by default uses Bing for search.

    Plan B.

    A simple web translation layer should be able to alter any web page to be used on any system. From the most basic option of turning it into an image file to acting as a 'translator' between specific user-side behaviours and more modern web page scripts and options. It would be a good way to test cut-down web interfaces on limited systems and would allow safe/secure surfing on all systems, not just retro, by filtering out all malign capability. You'd think there would be enough coders with enough spare time on the planet, to knock one out. The user could configure the range of options their system could or wished to deal with, and the software would intervene between the net connection and the browser.

    1. doublelayer Silver badge

      Re: Plan B.

      Yes, you can do that. The most common reason why sites don't load anymore is to do with encrypted connections, which are very common. Old browsers may lack support for the later TLS versions, may have outdated certificate management, or both. That's pretty easy to intercept and handle transparently.

      The reason that we don't go farther than that is that there's relatively little in it. It would allow you to browse on nearly any hardware, but only by getting some other hardware and manually configuring it. In many cases where that would work, it's often easier just to use the new hardware for the internet and either replace the old hardware or just use it for whatever purpose has caused you to keep it around.

      It also doesn't cause completely safe browsing. It would put an extra firewall on any exploits that use a script to try to interfere with the host, but the browser sandbox, while flawed, is frequently tested and patched in that respect anyway. You could accomplish the same thing by refusing to run any scripts, and your proxy will have similar problems; either a malicious script will be unable to affect the system, or it will be able to affect your proxy from which it can do the same things it could do on the local device. The more common security risks while browsing are either something a human typically filters, such as whether this site is the kind of place you want to enter sensitive information, or privacy-related, such as whether you're sending a copy of everything to an advertiser. A proxy can't deal with those any more than a local program can.

    Since Windows XP was discontinued in 2014, followed by Windows 7 in 2020, Microsoft’s support for their earlier OSes has significantly dwindled. As XP and earlier don’t officially support modern security improvements, such as the SHA256 hash algorithm required by modern SSL and Authenticode certificates as of 2019, much of the internet has become inaccessible to these devices. Adding insult to injury, Microsoft actively removed many downloads for XP and earlier versions in 2020. In effect, working with these OSes is now incredibly difficult.

    Windows Update provides many optional and recommended updates, in addition to drivers for your system, but Windows XP and 2000 can only install critical security updates through the built-in Automatic Updates feature.

    Microsoft should leap at the opportunity to expand on its side of the story. And officially "pardon" so to speak, the release of the WinXP and Win2K source tree a few years back, and treat it and this as part of the "playing with tech" community bundles they got started releasing about a couple of decades ago.

    Even going to the Internet with freaking DOS is safer that doing so with XP!

    By that way ever heard of Freedos?

    And the Web Browser Aracne?


    Have fun!

    Not only legacy hardware, but software also.

    You mention old hardware that won't run more modern Windows than XP, but there are also instances of software that won't run on more modern Windows. The ones I've heard of are industrial control applications that are effectively 'abandonware,' but still necessary to operate industrial equipment (boilers, plywood manufacturing, etc.).

    XP great for me

    Because I still play and very much enjoy Microsoft Combat Flight Simulator, using a game-port connected Microsoft Force Feedback joystick. None of those is supported by anything later than XP and I have a couple of Asus M5A7L PCs to keep me flying. Of course I have used a NLite to create a slim image and ghosted it, but every so often I rebuild using my genuine copies of XP. So really I don’t need this tool at all. I was just telling you what I do. Cheers.

      Re: XP great for me

      Do you mean: "Microsoft Combat Flight Simulator: WWII Europe Series" from 1998?

      If yes: You made me curious, so I tried it on Windows 11. It works, even the setup works. Though I had to select an 8.3 path on C: to install, but once installed you can copy it somewhere else. Even works in 4k, though with some graphical glitches. 2048x1536 is the highest resolution without glitches. Setting a frame limiter via GFX-card control panel recommended. DGVoodoo: Not tried (yet). xbox360 controller works too.

    I don’t understand. What is the difference between this new form of XP activation and just using the “windows XP CD key generator” from back in the day? I always remember the “windows XP cd key generator” crack to work successfully. Am I missing something?

    How about this then?

    I see a lot of people using a Raspberry Pi with one of these to act as a proxy for older machines. Heck, the provided screenshot shows Windows 98 and the original it was forked from shows Mac OS 9.2.2!

    I have (expensive) hardware that runs DOS. That I want to keep going.

    Legacy Update doesn't work for me -- on XP I only get a SOAP error "failed to parse SOAP' when it tries to do whatever it is trying to do.

    It's not about the internet

    Everyone always panics when I say "Windows XP." Guys.. NO ONE in this day and age will run XP with an internet connection. Why? Because NOTHING modern runs on XP (not even Firefox). *No* non-technical person would use XP, because using XP in 2024 is really, really difficult.

    I use XP to play 90's video games. It's on an 11" Atom netbook from 2007. All internet components have been uninstalled, all networking devices switched off.

    Here's the problem: One day when I think "Hey, let's try disabling hyperthreading and smartstep to see if this one game will run better." The moment I boot into XP, the slap to the face arrives: "Your hardware has changed. Please reactivate XP." Reboot into BIOS, re-enable those features, boot back into XP: "Your hardware has changed. Please reactivate XP." This is why reactivation mechanisms are still important. Old games simply don't run on modern systems without emulators, and emulators need INSANE single core performance. I just want an 11" netbook with 5 hours battery life that I can use in place of handheld console.
