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?

    Just throwing my hat in the ring. I am another who is experiencing this issue with MoUsoCoreWorker keeping my computer awake

    Installed the update (KB4023057) when it came out and continued to have this issue.
    I have since updated to 20H2 and the issue persists.

    I have gone through every "solution" in this thread and nothing has fixed the issue for me.

    Edition Windows 10 Pro

    Version 20H2

    Installed on ‎2/‎3/‎2021

    OS build 19042.804

    Experience Windows Feature Experience Pack 120.2212.551.0

    no you have not. if you try my solution, it will work.

    Lol. Cool man.

    I went through a this thread and copied each unique solution and went through them one by on.

    Not only did your solution not work, but it ended up preventing non-cumulative updates from installing at all.

    Thank you

    it WILL WORK. because it stops that coworker process. your computer goes to sleep after that. (if you had that same problem as mentioned in this thread. if you have some other problem with sleeping then you have to go to other thread or write your own.

    I have 3 Dell laptops all with latest windows and all updates. For the past several weeks I have been having issues with computers not going to sleep. All relate to MoUsoCoreWorker.exe, as reported in Powercfg.Requests, as others have said.

    Restarting the Windows Update procedure, as reported by others, would not clear the problem by itself. These additional steps did the trick for me:

    1. Power down the laptop.
    2. Remove all peripherals including docking stations etc.
    3. Unplug wall Power Adapter.
    4. REMOVE THE LAPTOP BATTERY.
    5. Press and hold the Computer Start button for a few seconds to bleed any residual power out.
    6. Reassemble the computer, and boot up normally.
    7. Rerun Windows Update. Computer may then reveal what is hanging up the system, and allow the update software installation to continue.
    8. When update is completed, Reboot normally, then run Powercfg /Requests. With luck you should then see there is no more MoUsoCoreWorker.exe flagged there.

    Unfortunately you will probably have to do this again after the next Windows Update screwup happens. I wish Microsoft would fix this.

    Hey there, I've been running into similar problems with spontaneous waking up from sleep. Only on a single sleep analysis report did it state the MoUSO as the culprit. Additionally, update KB4601319 keeps running into error code 0x8007000d regardless of my attempts at either downloading it or bypassing updates entirely.

    Ver 2004

    Build 19041.685

    Would love some help, thanks in advance

    Edit: Troubleshooting Power seemed to help, God only knows why other methods didn't. Hope to never need this again.
