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?

    Same here. I wonder if there is a separate problem, unrelated to Windows Update and this particular process? Mine will actually attempt going into sleep mode - it just wakes up again immediately. Not sure how that compares with others' experience here.

    In my case I stopped the Windows Update service which allowed the pending updates to install; the computer then went to sleep.

    But I'm sure this will occur at the next update, unless what I just installed patches the issue.

    Hi,

    My (currently working but who knows...) solution is to create a task (.cmd file) that is executed at each logon (using the Task Scheduler) and that contains these simple lines :

    @ECHO OFF

    powercfg -requestsoverride PROCESS "MoUsoCoreWorker.exe" SYSTEM

    To make things easier and cleaner, this .cmd file can be converted to an .exe file using the Bat to Exe Converter utility (https://www.majorgeeks.com/files/details/bat_to_exe_converter.html). This will allow to launch the command transparently.

    Anyway, this is an irritating bug because no one can say when MoUsoCoreWorker.exe will re-appear and post a new request. It's obviously related to recently installed or pending Windows updates but I can't find any pattern. MoUsoCoreWorker.exe is launched each time you check Windows Update in the system settings but it stay there afterwards (not necessarily posting a no-sleep request).

    So, Helloooooooooo Microsooooooooft!, time to wake up and fix this.

    If you are seeing this problem, the best solution (until an update is provided) is to restart the Windows Update service:

    Start > Run

    services.msc

    (Alternatively: Windows key for search, "Services", run the Services app)

    Scroll down to (or type) "Windows Update"

    Right-click and Restart

    Your computer will now be able to sleep for a while, at least until Windows Update starts pending on the next flight.
