I have a qualifying pc which is currently showing as being version win 10 pro 21H2.
Foe the last 18 months it has repeatedly aske me to to run the update to Win 22H2. This consistently fails. However, I have been receiving security and other updates for win 10 22H2 since 16-02-2023.
Every time I try to upgrade it fails.
I have tried everything possible I can find to solve it, clearing caches, removing update history, trouble shooting etc and I am at my wits end.
If I can't get it to win 10 22H2 it wont upgrade to Win 11 which I need and I do NOT want to have to clean install Win 11 if I can help it.
Any clues please are most welcome. I have exhausted everything I can find our there and nothing works. The only thing I haven't tried as a win 10 restore .
Help.

2024-12-23T16:33:55+00:00 I'd like to see the exact command you typed and the output.
Also, if you closed the Command Prompt window or shutdown the system after running the 1st set of commands, the 2nd set of commands won't work. They need to be run in a single Command Prompt session.
