Windows 10: Windows 11 activation fail since months

Hello,since a few months now already, maybe even half a year, I have the message in the bottom right that overwrites everything by saying "Activate Windows - Change to settings to activate Windows" translated by me from german.This message just occured one day, after I already had my pc since a year or something. In the settings it still just says that there was no product key found, "error 0xC004F213" and if I click the button to find a solution, it just says that my copy from Windows can't be activated, I shall make sure that I'm connected to the internet and try again or contact the suppo

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.

 

My PC suddenly says its not activated

I await instructions........

and apart from checking activation, I do everything else as per your suggestions......will in future check validated once a month.......

 

Windows 11 Update Failing

I have done all of the steps listed here and the KB5023706 still fails. I only recently ended up doing a complete repair (to get out of the Insider program that I entered by mistake). I have Windows 11 Pro installed - so if I download the ISO file will it recognize that this is windows 11 pro?
