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.

It is windows, so your deep debug/fix options are limited. I’ve had some luck with the ‘powercfg’ commands disabling sleep/wake for some sources.
The other suggestion, wake timers, is probably your problem, since windows wants to stay out of your way, and in their mind that means to wake up at 3am to take updates… what could go wrong?
It isn’t a huge issue but I just wanted make sure it wasn’t some weird virus or something that snuck its way in on a mod or something
Is there any risk to messing with the powercfg?
Unlikely a virus, but not impossible. Just more likely to be microsoft up to their normal tricks.
You can certainly make trouble with powercfg, but doing ‘powercfg /lastwake’ is entirely informational.
Some more ideas:
- Windows update appears to have a a way to log you back into you latest session
- BIOS power on after power loss setting, you might experience brownouts
- check task scheduler (taskschd.msc) for any entries that have permissions to turn on the system
- check the system or windows event logs for any mentions of reboot during nighttime
- disconnect ethernet cable for debugging purposes
- get a surge protector power strip with a switch
I had a similar problem. Tried a bunch of resolutions, fixes, or configs and none of them worked. Just bothered by it one day where I had just put the box to sleep and I just barely nudged my desk, wireless mouse lights up because it detected movement, box wakes up. My overly sensitive mouse was picking up shaking and waking up the computer because of the mouse input.
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.
Wake on LAN. You can turn this off in the power options I think, or in the BIOS.
As for automatic login, that I cannot say. Maybe you activated the option somewhere?
