Microsoft has rigged Windows 11 so it's not
supposed to run on this one.
Microsoft's forthcoming Windows 11 operating system has some
hardware requirements which are incompatible with many PCs
out there perfectly capable of useful service.
It requires, the same as the version of OS X for Intel-based Macs,
the newer UEFI type of motherboard. In addition, it requires TPM 2.0,
Note that the W11 TPM requirement accept "virtual" TPM that is
generated by the UEFI BIOS using the security "enclave" built into
*all* the cpus on the compatibility list. And we already know there's
going to be SOME exceptions to the TPM requirement, currently that's a
list of specific countries where it doesn't apply (due to goverment
It's also worth pointing out that a working TPM has been a hard
requirement for years now for OEM/SAs to be allowed to pre-install
Windows 10 (which they all do).
It's just DIY where it's not already mandated, the virtual TPM is
often disabled by default on consumer motherboards but since SA's also
use those motherboards it's available.
So if you do have a "supported" CPU in most cases it's just a question
of finding and enabling it in the BIOS. There are exceptions among the
older motherboards with supported CPUs but even those often have this.
And... while MS say it's a hard requirement and (somewhat!) enforce it
during testing they could easily change their mind.
Quite possibly more than once, I consider these kind of initial
announcements more of "trial balloons".
The list of supported CPUs will hit much more people since currently
you need a 8th generation Intel or Zen+ or later though MS has made
noises about possibly allowing 7th gen Intel and first generation Zen.
There's a LOT of 6th generation Intel (Skylake) still out there that's
perfectly fine machines and even 10th gen intel is only a minor
variant of Skylake...
OTOH, as you go back that far TPM 2.0 does get rare, so if they don't
change their mind it could be a big issue a few years down the line
(Win 10 now has a "free support ends" date somewhere in 2025).
If they do relax the TPM requirement it might end up like Windows 10
which technically require 4th generation Intel or newer, though Intel
3rd generation is allowed for Windows 8.x upgrades, but W10 will run
fine on Core2Quad's that PREDATE the entire "generation" numbering.
Or not, if they end up using an instruction not available on the older
chips (Sandy Bridge/AVX or Haswell/AVX2 is a few obvious possible pain
