Built a gaming PC back in 2018 (windows 10, GTX1080, i7, eset security).
For the past year or so it wakes up every now and then and for a few months it started waking up to my logged in desktop screen. Hasnt happened for about a month or so but it still eakes up even with my mouse and keyboard disconnected. I don't do any tormenting or anything sketchy. It's a really clean machine built for gaming, YouTube, office work stuff. I don't visit any "low brow" sites (that's what my tablet (not connected to the PC) is for). It didn't start happening after any specific download that I can remember.
Anyway, I can't find anything relevant online that helps me so I figured I'd ask here if anyone knows what this is about.
Windows, by default, doesn't fully power off when you tell it to shut down. Windows Update can wake it up and install updates, and then leave the computer running when it's done.
I believe there are some registry and/or group policy settings to disable this feature, but I'm not sure specifically what they are.
An option in the meantime is to hold down the left shift key while as you tell Windows to shut down. This should force a full power-off.
