And there are many windows insiders publishing ways to bypass secure boot checks in order to install (or create check free installers) Win 11 on Win 10 capable hardware that lacks secure boot or Trusted Platform Module 2.0
Starting with this in 2021 https://christitus.com/update-any-pc-to-windows11/ and likely (I'd have to check) integrated into Chris Titus's WinUtil by now.
Some combo of tweaking registry values or zero sizing a DLL has done the trick so far (but perhaps not into the future with upgrades and patches).
I think it's reasonable to say that for 99% of people this isn't a realistic solution. It's a time bomb that could go off at any patch. Related: https://www.tomshardware.com/software/windows/existing-worka...
It also shows that these machines are going to be rendered obsolete for no particular technical reason, other than presumably to sell more machines. Line must go up.
Now let's have a long prattle about our environment stewardship: https://www.microsoft.com/en-us/corporate-responsibility/sus...
Good for you. There is plenty of hardware out there without TPM 2.0, that is not allowed to upgrade, even if they in every other aspect are more than capable enough.
