Hi,
We have a Windows 2016 WSUS server that has been ok for many months, but recently when I log in I'm met with this error:

If I choose the Reset option nothing happens. If I reboot all is ok again for a day or 2.
I think it can happen if I approve updates on many OUs.
I just the Adamj Clean PS script once a week too.
I need to investigate these event errors

C:\Users\username\AppData\Roaming\Microsoft\MMC deleting WSUS didn't help.
UPDATE:
This may of helped, I used to have this set, maybe a CU changed it?
