Mouso core worker process

Question

My computer (Windows 10, 64-bit Build 19041) is constantly waking up from sleep and then going back to sleep for a short time only to repeat the cycle.  I ran sleep diagnostics on the Windows PowerShell as administrator i.e. powercfg /systemsleepdiagnostics.  The report from yesterday (5/31/2020) indicates that my computer awoke from sleep 50-55 times during the course of the day until at about 8:00 p.m., I decided that it was better to fully shut down the computer rather than have these continued cycles.  The common thread in all these awakenings from sleep is MoUSO Core Worker Process (MoUsoCoreWorker.exe). 

- Power Requests

- \Device\HarddiskVolume5\Windows\System32\MoUsoCoreWorker.exe | START TIME | DURATION | TYPE | TOKEN | | --- | --- | --- | --- | | 2020-05-31T18:18:53 | 0:00:01 | Execution | 0xffff8389192ab2e0 |

This executable is a Microsoft programming element. 

 Why is this happening and what can I do to eliminate this totally annoying phenomena?

Answer 1

Check and see if there is any update running on Windows?

Try run Windows Update and install all updates and restart your PC and see if problem persist?

Answer 2

I have the same problem. Does anyone know how to fix? There are no new update for now (2020-08-01) and problem still exists.

Answer 3

My computer is on Windows 10 Home Build 2004. I just had a similar issue that it wouldn't go into sleep. To check what was causing it, I opened a Command window in Administrator mode and entered

powercfg /requests

The only thing listed having power requests was

[PROCESS] \Device\HarddiskVolume6\Windows\System32\MoUsoCoreWorker.exe

USO Worker

A quick search on Google showed me MoUsoCoreWorker.exe is related to Windows Update, so I opened the Service Manager and restarted Windows Update service. I checked again with powercfg, and nothing was listed. My computer has been able to go to sleep.

I am not sure whether this issue is completely gone. But at least a quick restart of Windows Update service makes it go away.

Answer 4

I noticed that both my Wife and my PC didn't go to sleep last night. Both have this process running... No updates...
