POWERCFG -requests shows that System32\MoUsoCoreWorker.exe is the reason the computer never sleeps.
This article notes that restarting the Windows update service can fix it temporarily. It does clear MoUsoCoreWorker.exe from the
POWERCFG -requests report.
But hours later, MoUsoCoreWorker.exe is running again, and the computer still won't sleep.
Is there any better approach?
