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?

    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.

    Someone needs to tell them its only a temporary fix.  The process eventually comes back and prevents the computer from sleeping.

    After the Aug 11 updates (2nd Tuesday monthly), the MoUsoCoreWorker.exe process is no longer showing up under powercfg /requests.  And, if I put my computer into Sleep mode, it stays that way.  But, it still will not GO to sleep after xx minutes idle.  I just tried the KB4568831 fix, but I get a message: This update is not applicable to your computer.

    Update - Aug 18, 2020

    I discovered that when I unplug all USB A/V devices, the computer goes to sleep as expected. With those devices plugged in, powercfg /requests always shows their drivers as active.  This is new behaviour which began with Feature Update 2004.

    I tried (as someone in this thread suggested) powercfg /override, but that did not work for me.  I have to physically unplug the USB devices - really annoying.

    oh boy! you were right! my Bluetooth dongle (asus bt 400) caused issue when pc wont go to sleep after xx time

    UPD:

    run some tests:

     - plugged back (switched off) - goes to sleep

     - (on - not paired to anything) - goes to sleep

     - (on and paired headphones) - went to sleep

     - (on and paired to myPhone) - test is pending (can't connect)

    Go device manager, USB Serial Bus Controllers and right click on each device go to properties.  Then to go to power management tab and click the "Allow the computer to turn off this device to save power".  That'll help you from having to disconnect each time.  Try it with the other devices to if the given option is available.

    This worked for me! I have a Microsoft sculpt ergonomic keyboard and I needed to turn off "Allow the computer to turn off this device to save power" for the "Microsoft Hardware USB Mouse" device under "Human Interface Devices".
