On my custom gaming PC, I would sometimes leave it in sleep mode for extended periods of time (overnights, during the day, etc). On days I was home all the time, I never noticed it turn back on unless I did.


However, in the past 24 hours, whenever I put my PC into sleep mode, it will automatically turn itself back on for about 5 minutes, then sleep again. I'm not sure if it wakes a second time. I did notice that some updates were installed within that time, so I'm wondering if a setting got changed.


I did some reading up and took the following action:


1) prevented my network driver from waking the system


2) changed updates to once a week instead of every day (the time is set about 3 hours before this post). Did not restart after making these changes, though.


3) Installed all important and optional updates pending.


However, the problem persists. Powercfg -lastwake is showing \Device\HarddiskVolume2\System32\svchost.exe <wuauserv>. Research showed me that this was the the automatic update check, which I had disabled. Powercfg/requests does not turn up anything being used.


EDIT: have since restarted, also installed all graphics drivers. Computer will sleep, then wake after about ~8 minutes, go back to sleep, then wake after another ~8 minutes. Same message is displayed with -lastwake.
