Default Behavior

Power is a Win32 service. In Windows 11 it starts automatically during the operating system startup. Then the Power service logs on as LocalSystem and running in a shared process of svchost.exe. If Power fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the Power service startup failure.

Restore Default Startup Configuration of Power

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config Power start= auto
sc start Power

3. Close the command window and restart the computer.

The Power service is using the umpo.dll file that is located in the C:\Windows\system32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 11 installation media.
