Implications of hardware constraints within upcoming Windows 11 on Linux usage and adoption.
g000h Jul 1, 2021
I've been noticing various news stories and youtube videos talking about the new Windows 11 developer preview, and how it stipulates certain CPU models, having a working TPM unit, and Secure Boot enabled on your motherboard.

Some of the technical journalists have already manipulated the Windows 11 preview, so that it will install and work on older hardware, with non-working TPM, without Secure-Boot, and even work on Legacy boot mode (rather the UEFI). It appears that TPM and the other requirements are actually things that *Microsoft* wants to be activated, even if they aren't actually necessary for the operating system to work.

Microsoft usually does things like this, for the purpose of benefiting themselves. When Windows 10 came out, Microsoft were pushing for Secure-Boot on all new computer motherboards which was somewhat detrimental to Linux (at that time). The Linux community managed to turn it around though, and now many Linux distributions will happily install onto Secure-Boot hardware.

With TPM (Trusted Platform Module) acting as a microcontroller for performing cryptographic operations, I am wondering what implications there might be for Linux. Here's a few thoughts of my own:

- TPM can be used by the OS as an unique identifier for a computer, and so it can be used with the Windows' data telemetry to follow the hardware around (even if the OS gets wiped and reinstalled).

- Insistence on TPM, etc will stop older computers from installing or "upgrading" to Windows 11. This will force people to either seek an alternative OS (could be good for Linux) for that machine, or ditch that machine and buy a new one.

- TPM could be used for driver and software signing, and could potentially lock-down Windows more than it is now. By locking down, I mean that the current 'freedoms' that people enjoy today could be more limited with future Windows.

Does anyone have more thoughts on this? Will this be good or bad for Linux?

It all matters not a whit. Those who can’t upgrade will stay on win10 or buy new hardware.

Among Windows users, I believe the vast majority of them don't care or are even aware of those things. And among the few who complain, the vast majority of them will keep using Windows. I've heard people complain about Windows for more than two decades now and they still use it, whatever their reasons. Some might even be good reasons!

So, like @damarrin above, I don't think it will change anything. But I'd be glad to be wrong.

Quoting: g000hto follow the hardware around (even if the OS gets wiped and reinstalled).

they don't need TPM to do that, they already do that I know because now windows licenses are tied to your hardware ID's and modifying your PC hardware can sometimes invalidate your license... It happened to me with windows 7. I had to call MS to revalidate the license and explain them what I was doing.

Well, the fact that you change a piece of hardware in the machine and Windows thinks that you've copied/moved the OS to a new machine suggests to me that the existing hardware identification is somewhat flawed. For instance, if you update the firmware on a PC motherboard it could think you've changed the motherboard. The TPM identity is a bit more fixed-in-stone.

I was more interested in potential upsides and downsides of the new requirements (TPM, etc) going forwards and how that is likely to affect Linux into the future. For instance would having TPM, Secure-Boot and UEFI forced onto every future motherboard (i.e. no Legacy Boot being available) cause issues for Linux distributions? Would it prevent individuals from being able to roll their own Linux?

I was a little surprised that Microsoft is already announcing end of life for Windows 10, sometime in October 2025. There isn't long for these changes to begin affecting us.

I was more under the impression that the TPM was a requirement for OEMs that want to pre-install Windows 11 and not so much one for upgrading/installing Windows 11 on your own old hardware. Same with the CPU requirements. So I don't think it will have a great effect in the near future.

I hope I'm not wrong, because the last thing I need right now is all these Windows users rushing out to buy new hardware to upgrade to the latest and greatest.

Whatever the truth may be, I don't think it will affect Linux in a big way. Those happy with Windows 10 will likely be happy with Windows 11 too, if not more so. Those stuck with Windows for some reason or other will continue to be stuck. And if I were to get new hardware now it will sport some extra tiny bits of silicon (though I think TPMs are pretty standard already) that may or may not have a useful application under Linux.

Well, for us it means not much. Linux won't and doesn't require it and it's not something that will actually change things for us. Not even remotely worried about it, don't care really.

For Windows users, a lot will complain and stick to Windows 10. I don't believe it will actually do anything for Linux. You might see a few switch over but it will be in small numbers.

Those small numbers are how i got here.
Switched over when i saw the telemetry driven abomination that was Win 10

I have similar experience. Several of my relatives have installed linux on their older/newer machines. The trend with the problems is that they have some kind of issue with windows or how it works at least once a month. The only issues they had on linux is getting some of those big multifunction printer/scanner/fax devices working. Even with those the last HP device i installed for them was smooth sailing and didn't break on OS updates. But they still use Windows even in cases where their games and their browser experience is superior on the other OS. I think it will take linux coming preinstalled in a good chunk of computers and a good number of years before adoption can take off to double digits. And of course community effort, since that's all random people can do to drive it.

Is there anything the cattle won't do to get their fix?

It is so very merciful of Microsoft to let the cattle borrow Microsoft's computers. The masters have even gone out of their way to expose replaceable socketed CPUs with cores running as slaves under the true host. The cattle are allowed to install these CPUs but don't dare make any meaningful modifications. Within these walls, the good shepherd Microsoft allows their subjects such freedoms as an interactive GUI, the illusion of exerting control over the system, but, most importantly, the illusion of choice.

At this point I honestly don't care what happens in the normiesphere. Just grab your popcorn and put your feet up and let's all laugh at the fools as they are once again taken advantage of. What's that? Your slick new OS demands biometrics to be allowed to use it? Yeah, sure why not? Make sure to give master all of your keystrokes while you're at it. It will surely be used to improve your situation.

I am not sure on that one - Microsoft would rather have you upgrade to Windows 11, as they currently want you to upgrade to Windows 10, rather than having another "Windows-XP-Gate"

They will even happily let people buy some (illegal, as per the license) OEM keys for a couple of euros, rather than having people using their old OS. I guess the data they gather through telemetry compensate for the "lost" euros on the license price...
