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?

    I noticed the same issue with my desktop WIN10 2004, while the monitor would shut off as defined in Power & Sleep, the computer would not sleep automatically. I could make it sleep manually.

    I ran powercfg /requests as suggested- mousocoreworker was there.

    I looked in Update History, noticed that KB4586876 had failed installation a few times. Followed instructions to download it and installed successfully. After reboot, mousocoreworker was no longer there and the PC did sleep as it should.

    Will see if this lasts...

    Same -- no report of MoUsoCoreWorker requests (or any others) with powercfg, but still won't sleep on 2004. 

    MS apparently does not care about user experience, OR they lack the resources to investigate, which seems less likely, but their adamant refusal to acknowledge this problem and deal with it makes it appear increasingly likely that it's an active decision they've made. Whatever their reason for choosing to aggravate us to death with this persistent bug, an up-to-date sleep troubleshooter might help many of us.

    I have the same problem on all my PCs as well, since 2004 update, now on 20H2. However, MoUsoCoreWorker.exe is not showing up at powercfg -requests. PCs do not automatically go to neither sleep nor hibernate. Tried to install the KBs mentioned in some posts from the update catalogue, but it always says they are not for my computer. All optional updates in Windows Update installed.

    I found "Pausing Updates" until later time to do the trick for me...no more waking from sleep mode

    Many workarounds have been posted but I have posted what I experienced and will tell others that I messed with Windows Update to try and resolve this temporarily and I ended up having to do a repair install.  Remember any fix is only temporary anyway so why risk it?

    Microsoft needs to fix this permanently.
