Mouso core worker process

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?

    I have the same problem. I'm surprised it's still not fixed 🤯

    Since monthly updates should have been installed by WU this is the approximately two week window where sleep should be working.  At least its not this messing it up.   For now.  Just wait two weeks.

    I have Windows 10 Pro 2004, and have MoUsoCoreWorker.exe stopping my HP TouchSmart from going to sleep:

    C:\WINDOWS\system32>powercfg -requests

    DISPLAY:

    None.

    SYSTEM:

    None.

    AWAYMODE:

    None.

    EXECUTION:

    [PROCESS] \Device\HarddiskVolume4\Windows\System32\MoUsoCoreWorker.exe

    USO Worker

    PERFBOOST:

    None.

    ACTIVELOCKSCREEN:

    Anthony, you seem to misunderstand the results from this "powercfg -requests" query. What's shown above should be interpreted as "MoUsoCoreWorker.exe has requested that sleep be prevented" (not what you want).

    What you do WANT to see in response to a "-requests" query like this is the following:

    (note that nothing is listed as actively requesting that the system remain awake)

    C:\WINDOWS\system32>powercfg -requests

    DISPLAY:

    None.

    SYSTEM:

    None.

    AWAYMODE:

    None.

    EXECUTION:

    None.

    PERFBOOST:

    None.

    ACTIVELOCKSCREEN:

    None. 

    To tell POWERCFG to ignore MoUsoCoreWorker.exe requests, you have to enter a command like this:

    powercfg -requestsoverride process MoUsoCoreWorker.exe execution

    And then to see if the OVERRIDE request has been registered, enter the following command and observe that MoUsoCoreWorker.exe is listed.

    C:\WINDOWS\system32>powercfg -requestsoverride

    [SERVICE]

    [PROCESS]

    MoUsoCoreWorker.exe EXECUTION

    [DRIVER]

    A reboot may be required after the override request to knock the MoUsoCoreWorker off its pedestal.

    i have the same issue  - i have fixed it a number of times 

    • once by stopping the windows update service and trying windows update 
    • once by the windows scan now command 

    each time it works for a while then comes back - and can be seen in the power config requests list.

    i have just tried this command 

    powercfg -requestsoverride process MoUsoCoreWorker.exe execution

    when i checked if MoUsoCoreWorker.exe was disabled  - it was listed as disabled 

    i then rebooted the PC and ran the power config requests command again and got the following:

    PS C:\WINDOWS\system32> powercfg -requests

    DISPLAY:

    None.

    SYSTEM:

    None.

    AWAYMODE:

    None.

    EXECUTION:

    [PROCESS] \Device\HarddiskVolume4\Windows\System32\MoUsoCoreWorker.exe

    USO Worker

    [SERVICE] \Device\HarddiskVolume4\Windows\System32\SearchIndexer.exe (WSearch)

    Windows® Search is indexing

    PERFBOOST:

    None.

    ACTIVELOCKSCREEN:

    None.

    PS C:\WINDOWS\system32> 

     should this MoUsoCoreWorker.exe still be present in this list??
