Windows activation bug.

[Namlos]

A prompt for "you must activate windows" frequently show up, although my version is activated already. When I press the "activate" button the window that pops up shows that windows is already activated. 

This bug has endured over several updates.

Windows version 22H2, Build 22623.1095

For better assistance, can you share us the screenshot of "you must activate windows" prompt?

Is it 'Your license will expire soon' prompt?
