Recent Windows 10 issue, KB4517389, leads to a repeating loop that prevents the system from powering down.
Recently discovered that my machine didn't shut down by itself for several days. Both fans and CPU remained active. Checked Task Manager and saw the processor consistently using 20-30%. Ran 'powercfg -requests' from a command prompt and identified usocoreworker.exe as the blocker. This file appears linked to the latest Windows update package. Visited Windows Update and found KB4517389 stuck at 98% download speed. Tried stopping services with 'net stop wuauserve' and 'net stop bits', then cleared the downloads folder in %windows%/softwaredistribution/downloads. Restarted via 'net start wuauserve' and 'net start bits'. After updating, KB4517389 completed successfully and the system restarted automatically. The boot process showed a 'cleaning up' screen before the OS loaded. In the operating system, I confirmed usocoreworker was removed from 'powercfg -requests', and CPU usage decreased. Now the computer powers off properly. It seems many users face the same problem—Microsoft may release a fix for this update. Any additional tips to escape this loop would be appreciated.
When the computer isn't about to shut down, these solutions can assist: Review power settings, enable power requests, run the power troubleshooter, and install the latest drivers.
I received a fix from BleepingComputer. Downloaded the cumulative update KB4522355, which replaced the outdated KB4517389. After updating, Windows reached the "up to date" status, so usocoreworker stopped working, resolving the sleep issue.
