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).

This executable is a Microsoft programming element. 

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

    I installed the driver development kit pwrtest module that showed that it is definitely MoUsoCoreWorker.exe.    So no new info on how to fix it, but at least confirms what it is.

    The process is described here - but a bit of a hassle, must install Visual C++ and some development kits.  I am a programmer - so not a big drama, but perhaps a little frustrating for the uninitiated.....

    From blending together the .\pwrtest /monitor and .\pwrtest /requests logs, i have (Bolding Mine)

    Had the same problem.

    I checked for updates via Windows Update - it said - no new updates.

    I restarted the Windows Update service.

    I checked for updates via Windows Update again (2 min later), and now Windows Update finds new updates.

    It seems like windows update is stuck in a loop and thus the services keeps on staying alive. 

    I think that it probably fixed my problem. If anything new will happen, I'll update here.

    Restart Windows Update Service

    • Open Command Prompt in Administrator mode and execute this command: powercfg /requests
    • If you see MoUsoCoreWorker.exe listed anywhere, then it’s because of the Windows Update
    • Open Service Manager, locate Windows Update service, and restart it.
    • Rerun the Power Config command, and check if the listing of MoUsoCoreWorker.exe is gone.

    I tried installing KB4568831 It attempts to install, but it says this update is not applicable to my computer.  I'm running Windows 10 Pro, and Windows update says there's nothing new.

    I tried installing it twice, then Windows asked for two update restarts in a row.  I did so, but MoUsoCoreWorker.exe is still running and it won't auto sleep  (It does blank the screen though, but doesn't even log off,  Will try restarting the Windows update service next
