Ugh, been trying to upgrade my Dell Optiplex 7040 to Win11 for HOURS?

You could also try clearing the TPM from within Windows' security settings, then restarting and checking the BIOS again. Another option is to use the Media Creation Tool for a clean install, which sometimes bypasses weird upgrade checks. Let me know if that works.

This. You could also try clearing the TPM from within the BIOS, as sometimes that gets it to be recognized properly.

+1 Sometimes a BIOS update from Dell's website can resolve those stubborn compatibility flags.
