My Windows 10 machine would sometimes automatically boots up at night for no apparent reason. Is there some sort of log that I can check that would give an explanation?
- Report information about the last event that woke the computer:
- Lists devices that are user-configurable to wake the system from a sleep state:
POWERCFG /DEVICEQUERY wake_programmable
- Lists devices that are currently configured to wake the system from any sleep state:
POWERCFG /DEVICEQUERY wake_armed
- Returns all devices that support waking the system from any sleep state:
POWERCFG /DEVICEQUERY wake_from_any
After finding culprit maybe you can remove the SW or HW. If not reference @Alex's answer to disable wake timers in power settings GUI

One of the multiple reasons could be the Wake-On-LAN feature.
Is there any mechanism in your network that would send out Wake-On-LAN packages? Also is your computer configured to respond to such packets?
