Default Behavior

Power is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Power service is running as LocalSystem in a shared process of svchost.exe along with other services. If Power fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the Power service has failed to start due to the error.

Restore Default Startup Configuration for Power

1. Select your Windows 10 edition and release, and then click Download.

2. Save the Win10_Power_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The Power service is using the umpo.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
