Don't waste your time on this HealthCheck...

For example, this could refuse to run, claiming
"Your organization controls Windows Update". I had to change drives
a couple times, until I found an OS ready to roll.

https://aka.ms/GetPCHealthCheckApp

Name: WindowsPCHealthCheckSetup.msi
Size: 14,348,288 bytes (13 MiB)
SHA256: DF9F81457E7FC9D670EB9A329ED55E3D7BA2DE4DC4D71E7FCC246239D27BEF04

Yellow:   This PC must support Secure Boot [UEFI BIOS feature, code for TPM based attestation]
Yellow:   TPM 2.0 must be supported and enabled on this PC.
          TPM not detected.

Red:      The processor isn't currently supported for Windows 11.
          Intel Core i7-4930K CPU @ 3.40GHz

          ["Not on the approved list" <snicker>]
          [Lacks MBEC support (now listed on ark.intel.com entries which support the feature) ]
          [Does have POPCNT/SSE42 instruction (installer blocks without this) E8400 lacks this ]
          [Does have VT-X Support (sandboxing, WSL2, HyperV) ]

Green:    There is at least 4 GB of system memory (RAM). [Needs more really]
Green:    The system disk is 64 GB or larger.
Green:    The processor has two or more cores [Six cores is a good number].

Install the OS on a capable PC, move the hard drive over
to the non-capable PC. What happens ? It turns off a bunch
of features and boots like it was Windows 10.

For example, the PC in the above description, is running Windows 11 right now :-)

You can build a https://rufus.ie USB stick with modified ISO contents
and run the Setup.exe from it, and install Windows 11. the interface of Rufus
has some tick boxes for disabling blocker checks of various sorts. If you
have an E8400 or an E7500, those don't have POPCNT, and Rufus does not disable
that check, because if you bypass that check, the OS will (it is claimed) crash
on the next boot.

If you did a legacy (MSDOS) install of Windows 10 back in 2015, or you installed
windows 10 32-bit, these would be examples of bad things. There is an assumption
of a GPT disk setup, and a 64-bit OS. You can use MBR2GPT.exe utility, to switch
over to GPT, but that only works for the simplest disk setup, and it is not
without issues. So there are some issues that aren't "health issues" but they
will never the less cause a rollback or a refusal.

Do a full backup of your hard drive, before acting, and make sure no excess
disks are present (depending on the kind of install you end up doing). The
usual rules about "safe" install practices apply.
