My PC is restarting

This event informs you that your computer has restarted, but that is not the cause.

You should check the warning or critical events in the 5 minutes before the restart.

Sometimes a truth escapes you because it is insignificant. It can also happen that you do not see it due to its obviousness and enormity!

Hello,

Are you sure it's this event that caused your PC to restart? Because this only pertains to the restarting of a service...

In any case, it's better not to disable it
