The PC Health App can spell it out a bit more than the Windows Update
box does. This will only be in Win10, if you installed it

   C:\Program Files\PCHealthCheck\PCHealthCheck.exe    866,224 bytes  (2022)

But generally speaking, they didn't make much of an effort to
spell things out.

POPCNT got added to this one ("coreinfo.exe"), but I don't see an MBEC.

   https://learn.microsoft.com/en-us/sysinternals/downloads/coreinfo

For MBEC (a dependency but not a prerequisite), the Intel entry for
your processor will only have an entry, if the device
has the feature. They don't like to list MBEC and No in the same
sentence.

https://www.intel.com/content/www/us/en/products/sku/236773/intel-core-i9-processor-14900k-36m-cache-up-to-6-00-ghz/specifications.html

   Mode-based Execute Control (MBEC)      Yes

Microsoft also has a "list of processors" but I don't think any
installer consults such a list. It's more likely to be "by measurement".
When W10/W11 boots, features are turned off "by measurement",
to ensure it boots. The claimed exception is POPCNT, where if you
don't have it for an OS that requires it, the OS crashes. I still haven't
tested that, but I do not doubt the prediction. I don't even think
they execute the POPCNT -- all they have to do, is use a privileged
instruction to check processor features, and if the processor
does not have SSE 4.2, then you don't have the flavor of POPCNT
they really want (SIMD version). I figured this was for some sort of
crude neural network code or something. The requirement to me, seems
rather pointless. It can't perform well enough to do anything,
and could be replaced with a macro instead (with a speed penalty).

If you are running Win10 32-bit, there is no in-place upgrade strategy
for you. win11 is 64-bit only. That's why the PCHealth above is in
the 64-bit Program Files :-)

I would not expect anyone in the audience, to be wedged in such a corner :-)
I don't even know what it says, when you present that case to them.
I probably have W10 32-bit VMs, but those wouldn't work right for
an OS offer. It would have to be tested physically.
