So ever since I upgraded my Win10 Pro from 1909 to 20h2, my screen saver wont kick in when idle time has passed, I run a server 2016 essentials at home with gpo setting the idle time to 20 mins. I know the gpo works on the other computer in the house. But my primary desktop won't lock when the idle time occurs. I trying to figure out why but have not found a reason. GPO is applied. Windows 10 shows it managed by the domain. I have tried different accounts, they all behave the same way.
I am starting to wonder if my scheduled task to trigger shadow copy might be the culprit but it worked just fine before the update. And now it is too late to go back. I considered using my backs up but that just creates other headaches I don't want to deal with right now.. If I can resolve this I would be better off starting fresh and just trying to salvage my settings from my the current profile. I have not found any errors in the events to indicate something is blocking it. I was actually tweaking a shadow copy task when it made me wonder if that might be the issue but I don't see why. On our work domain shadowcopy doe snot mess with the timeouts on the servers so don't see why it would on windows 10. Its not the mouse I already tried leaving it disconnected over night only to find windows still unlocked. I have run out google searches trying to figure this out.
