How to find which service wakes up the machine from hibernation?

Question

Iron

Windows 10
Already when I set everything up as soon as I installed it, the computer hasn’t turned on for half a year now. But today he wakes up again from hibernation.
The event viewer says that the source is unknown, and the local service is listed as the user.
Is there a way to find out more precisely what exactly wakes up the computer? And then I already dug everything in the task scheduler and did not find it.
UPDATE: who will look for the answer - chop off the software that hangs in the background in turn, so you will find the culprit. For example TimViewer !

Answer 1

A method from somewhere on the Internet:
You need to find out what the computer wakes up from, you can do it with the command (from the admin):
1) powercfg -lastwake
2) Next, look at the list of devices that can wake it up: powercfg -devicequery wake_armed
3) Through the device manager, After selecting the desired device, go to the "Power Management" tab and uncheck "Allow this device to wake the computer from standby".
If this does not help, we look at the rest of the possible wake timers: powercfg -waketimers
The most common case for Windows 10 is scheduled defragmentation and PC maintenance at night, you can turn it off here:
1) Go to the Task Scheduler
2) NT TASK\Microsoft\Windows\UpdateOrchestrator\Reboot
3) Right click > Properties > Conditions
4) Uncheck "Wake the computer to complete the task"

Answer 2

View the log in the "system" section - look for an event coinciding with the start time of the computer.
