Random Windows Tip: My PC Wakes Up In The Middle Of The Night And I Don’t Know Why
Read Time:1 Min, 14 Sec
The way our house is currently setup, my office is in my/our bedroom. I know, not ideal. Anyway, at the end of the work day, I usually just put my laptop to sleep and then in the morning wake it up. That way, everything is just as I left it. However, for the last few weeks, every now and then, the darn thing wakes up in the middle of the night which causes all the monitors to come on. There is nothing like being woken up at 2:37am to 
in your room.
Well, after doing things like turning off the monitors and closing the laptop or unplugging the laptop so that it is on battery and won’t wake up, I think I may have found the answer. There is a Task Scheduled to check for Windows Updates (\Microsoft\Windows\UpdateOrchestrator\Schedule Scan). I tried to disable or delete it but I have been unable to because of a permissions issue, even as admin.
I think I found a solution: You can remove access to the file that it runs by running the following from an admin command line:
takeown /f "%WINDIR%\System32\UsoClient.exe" /a icacls "%WINDIR%\System32\UsoClient.exe" /remove "Administrators" "Authenticated Users" "Users" "System"
You can still do Windows Updates, they just need to be done manually. I don’t know if this will work for everyone or if it is the best way to do it, but it seems to be working so far.
