Windows 10 2004 version is rather a buggy mess in my systems across the board. Also noticed random restarts and slower boot time.
Needless to say, since I have 2004 on 2 systems in less than 10 days (this is the timeframe Microsoft allows you to roll back, granted you havent deleted the windows old folder), I was able to revert back to 1909.
Afterwards, I disabled Windows Automatic Update system (WAU) and using WAU Manager as a replacement.

Systems are now back to normality.
