Almost Daily Activation

My windows 10 home version 1909 64bit is causing me grief! I upgraded from a genuine windows 7 not long after windows 10 became available. Everything has been perfect until a few weeks ago when it displayed that it was no longer activated. I ran the troubleshoot on the activation page in settings / update and security and it reactivated windows. Unfortunately almost daily I get the message again and have to run troubleshoot. Eventually I contacted microsoft help who did all sorts of things remotely which I hoped would cure the problem but it hasn't.

Here are a few clues in the hope that someone can help me:

1. I have found the installed key using showkey plus and it states the key is a generic key which requires a digital licence for activation. Obviously when I run troubleshoot it works so the digital key must be somewhere.
2. If I go to control panel and open the system folder, hoping to see windows activated and the key, it instantly deactivates windows! I then have to go back to settings / update and security / activation and run the troubleshoot again.
3. I have run sfc / scannow and dism and there are no issues
4. I have reinserted the serial key in product update but that does not help
5. I am using a microsoft account to log in not a local account
Help!!

You probably have read through this thread "Activate Windows" does not stick and seen we have not found a solution

I can't replicate it - so just guessing...

... try uninstalling the 1909 update (the theory being that due to the build confusion it causes there may be activation components breaking)

Thanks for the advice. I will put this on my list of what to try. I was hoping not to do this but maybe to wait for the next update which might cure the problem
