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).

- \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 found a simple steps to troubleshoot this issue. Works on my 4 different PCs.

    (I'm not sure about the English names of Settings app...)

    1. Settings=>Windows Update=>Other options=>Set delay of Windows Update on max days
    2. Close Setting
    3. Wait some time (~1 min)
    4. Open Settings again=>Windows Update=>click on Resume Windows Update button at the right
    5. That's all.

    Sorry, I have only Pro version. I don't know if the Home version has an option to pause updates.

    Thank you UtopiaOpera1, I tried your fix that also does not solve my problem. At this point, I have zero patience left for this type of time draining troubleshoot. For anyone interested in a manual solution, I simply set my Power button to trigger Sleep mode and hopefully remember to turn it on whenever I m away from the PC.

    The setting is available from Additional Power Setting. Click on Choose What the Power Buttons Do, to bring up a list of options (Do Nothing, Sleep, Hibernate, Shut Down). I chose to put it to Sleep and that works for me.

    I believe Hibernate option works similarly but is designed for laptop closing and opening the lid.

    As previous users have noted, the culprit is usually Windows Update. CMD "powercfg -requests" shows this to be the only issue:

    EXECUTION:

    [PROCESS] \Device\HarddiskVolume3\Windows\System32\MoUsoCoreWorker.exe

    USO Worker

    Before fixing it, Windows Update show no updates in the queue, but restarting the Update service then shows there is an update ready to download. Today it was the Adobe Flash removal tool, but previously there were other Quality updates stuck in the pipeline.

    A constant issue since "Feature update to Windows 10, version 20H2".

    Microsoft...PLEASE FIX!

    Here is the fix (worked for me at least).

    tl;dr [Run the Windows Update Troubleshooter]

    1. Open 'Troubleshoot Settings' (Win Key, start typing it, press it)
    2. Press 'Additional Troubleshooters'.
    3. Press 'Windows Update'.
    4. Run the update Troubleshooter.

    Mine found errors and resolved them.

    1. RESTART.
    2. Open CMD in Admin and run 'powercfg -requests' to see if the glitch is still there (mine had gone at this point)
    3. Run Windows Update and look for updates. Now, when I opened mine, there was an error shown 'Failed to Install', I think this was the issue causing that exe to run constantly, and it was the Adobe Flash removal update!

    Let that update now hopefully run correctly, and when it says update installed, go back to CMD, press the up arrow key to show last command and press enter to see if the exe isn't listed... hopefully it isn't and all is back to normal.

    If memory serves this isn't the first time I've had to run this same process to fix an update issues causing sleep errors.
