back to article Microsoft quietly erases Windows 11 TPM 2.0 bypass workaround from help page

For the past three years, Microsoft documented a way to run Windows 11 on PCs that lack Trusted Platform Module 2.0 hardware – but that workaround has now disappeared from its help page. A Trusted Platform Module (TPM) is an all singing, all dancing security component that can store sensitive secrets such as encryption keys, …

      There are valid use cases for disabling the TPM in BIOS - the most pertinent of which is to prevent the installation of Windows 11.

        It's not only that that stops it. I run KVM on a linux server (rocky 8 if relevant) at home, and provide a vTPM2.0 module to a Win11 guest I have as a remote access desktop on there. The install of 24H2 still would not proceed without "fudging" it as the processor I have in there is a socket 2011-3 variant, none of which are supported by Win 11. It worked initially when I installed last year using the server hardware check workaround, however I doubt that would work with 24H2 now.

    MS doing their best to slow down the adoption of Windows 11

    Enforcing the TPM 2 requirements will slow down the adoption of Windows 11 so why are MS doing it ?

    Possibilities that come to mind

    1) MS is getting a kickback from the makers of new PCs

    2) MS plans to use the TPM to block other software (eg Linux, LibreOffice, Firefox, Thunderbird etc) that competes with MS software

    3) MS plans to use the TPM to embed an undetectable backdoor

    I can not think of any reasons for requiring a TPM 2.0 module that would actually benefit the users of Win 11 - can you ?

            The fact that the senate is split 50:50 is not a happy accident that would be spoiled by the addition if a left-leaning 51st state. It is a natural consequence of a first-past-the-post voting system. You always end up with two main parties and they want to make as few policy compromises as possible to gain power. Therefore, both are aiming to attract 51% of the seats. Larger majorities (which certainly do happen) merely indicate that the losing side really fucked up.

            Update: I forgot to add that with both sides chasing 51%, we should not be surprised that the election campaigns are basically a scrap for that 2% overlap and the other 98% are ignored.

      I would suggest that they are using TPM to (attempt to) plug an otherwise intractable security hole in their shite. They can't (or can't be arsed to -- that is an inclusive OR) fix it themselves, so they rely on hardware to (maybe) do it.

      This does not in any way remove the possibilities that @Duncan MacDonald posited.

      Re: MS doing their best to slow down the adoption of Windows 11

      Do you have any idea how one would use a TPM to accomplish either goal 2 or 3? That's not what TPMs do.

      To be boring, probably the reason they put in the requirement is that they turned on Bitlocker by default, Bitlocker requires some version of TPM to have drive encryption without requesting a password at startup, and they want to be able to cut 1.2 compatibility out of their code at some later point without having annoyed users yelling about how their update is breaking drive encryption. The requirement, along with the restrictive processor requirement, is generating a lot of ewaste that I disapprove of. Again, I think this is probably less malicious than lazy, because it enables them to compile for newer instruction sets whenever they want, but machines with Skylake CPUs are not out of date. Microsoft used to be much better about allowing the user to determine when their hardware was old enough to need refreshing; Windows 7 or 10 wouldn't run well on something ancient, but it would run. Unfortunately, Apple has done similar things with their shortening Mac OS lifetimes, and just like Windows 11, a simple tweak to the installer makes the modern OS install just fine, demonstrating how unnecessary the hardware requirements are.

      1. collinsl Silver badge

        Re: MS doing their best to slow down the adoption of Windows 11

        I agree with your points but would point out that this is just Microsoft returning to form. The hardware requirement upticks between versions always used to be fairly reasonable (think XP to Vista or 98 to 2000) however with the massive increase in computing power available in each generation of desktops people tended to go with the flow as the OSes became available - they would change OS to a later one as they upgraded their PC, and with the online world being less developed and mattering less they didn't see the issue with taking older OSes online for brief periods.

        These days however windows 7 to 10 have had basically flat hardware requirements thanks to the fact that hardware has become so powerful over the past decade or so. Now that the performance curve is flattening out again older PCs can keep up with newer OSes however Microsoft doesn't make money if people aren't upgrading, and they want to cut costs and simplify development (along with forcing people to buy new OSes via buying new hardware) so they are introducing arbitrary cutoff points in hardware support, which previously would have been seen as part of a natural upgrade cycle to get a better performing PC, but these days is out of step with hardware performance and just looks arbitrary and wrong.

        No one in the first world moves to Linux because they don't have to "pay". They move because they want full control over the software running on their PC. That's a valid goal too, but wasn't the goal of the guy who switched to Apple.

I'll happily conceded that Windows still do the best commercial and business-oriented desktop OS (not to mention gaming on PC), Apple make the best design and creative machines (although there's less difference now than there used to be in that area), and Linux is the best server OS for the majority of use-cases which don't involve terminal services or active directory (since AD has many useful features built on top of LDAP).

    Does Anyone Actually Need A TPM ?

    Whenever a general person purchases a PC, a TPM module is never an issue that they are aware of, let alone think about.

    Since 2016 i have run Linux as my main OS, so not sure if there is something specific that Windows must have to function securely (ha ha ha ha ha) that was required before.

    Microsoft has a monopoly, and it is abusing that monopoly.

    TPM and Linux

    First of all, TPM is absolutely the most pointless tech ever devised, especially as there have already been multiple successful hacks.

    As far as I can tell, the sole purpose of TPM is an attempt to lock people into Microsoft's ecosystem ("He who controls the bootloader...").

    Having said that, allegedly there is a way to use Linux on hardware infected with TPM (enabled).

    I read the docs for this, several times over, until my brain melted. Did I mention I'm a Gentoo user (and Void Linux) for past 20 years, so not exactly a noob, but this is honestly the most perversely convoluted, overengineered and complicated shit of all time.

    Frankly it would just be a whole lot easier to disable TPM, and never install Windows. Ever.

    Bonus points if I can rip that shit out of its socket and smash it with a sledgehammer.

      Re: TPM and Linux

      I don't know what you think a TPM does, but it sounds like you've misinterpreted it. Many Linux systems use a TPM quite intentionally for the same reasons that Windows does. If you use LUKS volumes, one of the most common configurations is to use a TPM so that the volumes are linked to the computer in which they were created. This means that, if I get a copy of your drives and start brute forcing your key, I'll almost certainly fail because I don't have the part stored in the TPM. Of course, you can use LUKS without a TPM if you want, but it's really not unusual to use it. A TPM is a relatively dumb piece of hardware/software and like any other part of the computer, you could use it for malicious purposes. Since it can be used to run only a certain set of software at boot, you could use it to make sure the computer doesn't boot anything except Windows. However, if you're concerned that they'll do that, it's worth considering that there have been TPMs since 2003 and can you point to any time when they did this?

        If I have LUKS volumes bound to my motherboard via a partial key stored in the TPM chip, then if my motherboard fails, how do I make those volumes work with my replacement motherboard?

        It appears that using LUKS with TPM is setting nyself up for a denial-of-service situation (either "natural" or "hostile").

          Re: TPM and Linux

          Those being tied together is the entire point. You respond to the motherboard being broken by restoring your backups to the next version. Maybe you don't want that, which is why you would choose not to use it (you still have backups, though, right), but the unrecoverability if the drive and motherboard are not together is considered an advantage to those who use this method because it becomes more difficult for a misplaced or stolen drive to be cracked. As usual, this is just one option, although quite a popular one.
