You might find a thread I created about that subject entertaining:
By tweaking the Registry, I managed to install Win 11 on my 11 years old netbook. MS is well known for its tight security /s.
While I did not keep that installation on the netbook (which is currently running LinuxLite), I still keep on updating Win 11 on the other installation on the 10 years old Acer Aspire just out of curiosity.
