Windows 10: I upgraded my Windows 10 Pro installation to Windows 11 Pro, and now it can't detect TPM...

Hello,I have a peculiar issue where after upgrading to Windows 11, it can no longer detect TPM 2.0, and thus doesn't offer feature updates like 23H2, but regular quality cumulative updates install just fine.Windows 11 Pro, build 22621, and here's my update history. Clearly TPM has been detected just fine before I upgraded into Windows 11 just over a month ago. to be continued below screenshotdates are in international format, DD MM YYYYPC Health Check also says it can't find TPM, and ditto with the upgrade assistant download and with the latest ISO installation media. All claim I have no T

Clean Windows 10 (?PRO?) install

I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.

 

Clean Windows 10 (?PRO?) install

As far as I am aware there is no Windows 10 Pro version.
But I'd be happy to be wrong.

 

Windows 11 Pro Upgrade from Windows 10 Pro Edition

No but after it installed the malfunctioning Windows 11 upgrade it was listed as Windows 11 Pro. Microsoft Windows support advised I reinstall Windows 10 Pro and said that Windows 11 is really only meant for new PC's that come with it preinstalled. MSI website doesn't list my 2020 GT76 Titan dt-039 notebook on their Windows 11 upgrade eligibility list so I guess that's why the Windows 11 Pro upgrade failed. I suggest being careful with trying the Windows 11 upgrade despite it stating my notebook was capable of running Windows 11 it was wrong. Luckily I have the original Windows 10 Pro USB Flash drive because the Windows 11 Pro upgrade was so incomplete I had no way of reverting notebook back to Windows 10 without reinstalling from a USB Flash.
