Default Behavior

The Microsoft UEFI Driver service is a kernel device driver. In Windows 8 it will not be started until the user starts it. If Microsoft UEFI Driver fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the UEFI service hasn't been started.

Restore Default Startup Configuration for Microsoft UEFI Driver

2. Save the Win8_UEFI_Service_Startup.cmd file to a local storage device.
