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?

According to the information supplied by the poster, it's most likely that Windows was waking up the computer at night in order to install new updates, as are the default settings of Windows Update.
Once all updates have been installed, the computer goes back to sleeping happily and doesn't wake up any more. Until the next time.
Finer control over Windows Update is found inSettings > Update & Security > Windows Updateand inPower Options > Change plan settings > Change advanced power settings, under Sleep, Allow wake timers.
1Just run this command in an elevated command prompt:
powercfg /requestsoverride process "\Device\HarddiskVolume3\Windows\System32\MoUsoCoreWorker.exe"Note that the part in quotes needs to match the path from powercfg -requests
2For me the Solution was:
powercfg /requestsoverride process "MoUSO Core Worker" execution
powercfg /requestsoverride process "USO Worker" execution I have had this same problem on my PC on Windows 10. Could NOT figure it out and did research for hours. Pulled up command prompts and only thing it said was I needed to preform an execution for mousocore worker. Even tried an override code - nothing worked.
Finally I got the bright idea to go to task manager find MoUSO Core Worker Process (MoUsoCoreWorker.exe) running under background processes and right click to end task. Working fine now and my computer went straight to sleep after. Hope this saves some time and frustation for someone.
