The 24H2 Update was not offered to me, although I run Parallels Desktop 20 for Mac Pro v20.1.2 and had an up-to-date Windows 11 23H2.
I did the above registry hack.
I restarted Windows.
The 24H2 update was then shown for update and update began downloading and installing.
Restart of Windows to finish installation.
Update ran successfully. System info shows:
Edition Windows 11 Pro
Version 24H2
Installiert am 02.12.2024
Betriebssystembuild 26100.2314
Leistung Windows Feature Experience Pack 1000.26100.32.0
Another restart to update Parallels Tools.
Done.
Thank you for the registry hack!
