Windows 10 keeps restarting my PC after shutdown

Solution 1:

I found my computer restarting by itself and I found the problem.

1. Go into my computer right click properties
2. then get into device manager.
3. Under network adapters find your driver right click and make sure that under power management tab you unclick let device start up computer.

It seems that when my network computers tried to talk to my machine it restarted. By the way, I also changed the power setting first to stop quick restart but that alone did nothing on its own

Solution 2:

The problem was

Windows control panel: Settings > System > "Power & sleep" > "Additional power settings" under "Related settings" > "Choose what the power buttons do" > "Change settings that are currently unavailable" > uncheck "Turn on fast startup (recommended)".

on shutdown there was an application which was slower and closed at last, this triggered the "awake" on sleep mode again, resulting in a "reboot" or wake-up.

With this setting the slower application doesn't wake up the pc again. Another solution is to remove the application that causes this.

Solution 3:

1. Click start button/icon
2. Search for cmd
3. Right-click on icon and select "Run as Administrator"

4. At command line type the following:

   powercfg h off
   

5. Press Enter

6. Type exit and press Enter

Now try to shut down through start button/power/shut down and see if it works.
