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'm also getting the same problem and my PC won't go to sleep. To get rid of "MoUsoCoreWorker.exe",

    1. Edit the power plan (Change advanced power settings)
    2. Expand "Sleep"
    3. Expand "Allow wake up timers"
    4. Change "Setting" to "Disable"

    If the "Setting" is "Important Wake Timers Only". "MoUsoCoreWorker.exe" will also appear. This is plainly stupid on Microsoft's part. "Important Wake Timers Only" should only allow the PC from being woken, but instead it is denying the PC from sleeping.

    Thanks Programatix, I tried your method but it did not work for me. the MoUsoCoreWorker.exe is still running, and I still have the same mouse problem. I have tried switching to another mouse and keyboard, same issues.

    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.

    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!
