Mouso core worker process

Again, with all due respect, although you may have hit upon one of a million reasons why windows may stay awake or a PC may wake from sleep, the main thread of this issue is the specific case where MoUsoCoreWorker.exe is keeping a PC awake where the million or so other reasons are not.

Sure, a rogue WOL packet might wake a PC, or leaving a Word file open on a UNC share might prevent it going to sleep, but the overriding issue here is that each patch Tuesday the MoUsoCoreWorker.exe will spring in to action (no matter if you 'fixed' it last month or not) and prevent your PC going to sleep again!

That is the main issue we need MS to fix (regardless of whether this thread has helped with one or two of the million other scenarios along the way).

With all due respect, I don't think it was. Maybe solved until the next patch Tuesday, but not solved permanently...

Had the same problem.

I checked for updates via Windows Update - it said - no new updates.

I restarted the Windows Update service.

I checked for updates via Windows Update again (2 min later), and now Windows Update finds new updates.

It seems like windows update is stuck in a loop and thus the services keeps on staying alive. 

I think that it probably fixed my problem. If anything new will happen, I'll update here.

My problem was solve with the above solution

I think it is still worthwhile to keep this discussion here. I thought my issue was with MoUsoCoreWorker.exe because that's what I saw in the powercfg.exe output when the display would instantly wake back up from the sleep that was just started. However, this was a red herring, at least for me. The real issue was the USB device. I discovered that because of a suggestion in this thread.

If you run 'powercfg /devicequery wake_programmable' from an administrator command prompt, you will probably see one or more network adapters named something like 'Intel(R) I211 Gigabit Network Connection' or 'Intel(R) Wi-Fi 6 AX200 160MHz'. Try using 'powercfg /devicedisablewake <devicename>' to disable wake for each one. In my experience, wake-on-LAN is enabled by default for all network adapters, and any network with other devices on it will constantly wake your device from sleep unless you're in a carefully configured workplace where everything is hooked up to switches.

Can this discussion be moved or its own thread started?  It is taking away from the point of this thread.

This thread is about MoUsoCoreWorker.exe which has been preventing sleep on most if not all Windows 10 computers for months with Microsoft doing nothing about it.
