In case you haven't noticed, MoUsoCoreWorker.exe is back preventing your computer from sleeping. Again.
Actually, it's not, this time. My computer, slept and resumed from sleep correctly for about two months and then suddenly stopped this week. It would shut down most of the way and then pop back to full "on." To my surprise, powercfg /requests showed nothing. Update history showed nothing -- no failed updates during the 4.5-month life of the machine.
However, I remembered a few contributors to this forum mentioning that they'd solved their problem by installing an optional update. I looked. There were three, including one related to Intel Bluetooth, one relating to Intel WiFi, and one relating to the AMD chipset. I checked all three and let it do it's thing. When it finished, only one had actually been installed, the Intel-WiFi update. The other two remained in the list of uninstalled optional updates, but that one WiFi update was all it took to get the computer sleeping perfectly again.
So, even if MoUsoCoreWorker.exe doesn't show up in powercfg troubleshooting, the problem may still have something to do with MS Update. I don't think the update service, itself, was the culprit, but there was an optional update that was needed. Are all driver updates listed as "optional?"
