Seems like you've looked into it. Thanks for reading!

The issue was it had v 1.2 and Windows 11 requires V 2.0. I have an ASUS B365, which shipped with TPM. I doubled checked tpm.msc, too.

I didn't know about the remote desktop being removed. Haven't tried it yet. I wonder if they will introduce something else? I have Linux dual boot, a NAS server, and also use office 365 and clouds, so if I want to do remote work, I can use those.

Actually, the reason I upgraded was to do stuff using WSL 2 and VSC which required enabling 'virtualization' in my bios. That was off by default. I decided to upgrade the BIOS while I was messing around in there because I knew I would need to for Windows 11.
