Default Behavior

The Microsoft Software Shadow Copy Provider service is a Win32 program that can be started by the Service Controller and that obeys the service control protocol. In Windows 8 it will not be started until the user starts it. When the Microsoft Software Shadow Copy Provider service is started, it runs as LocalSystem in its own process of svchost.exe. If Microsoft Software Shadow Copy Provider 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 swprv service hasn't been started.

Dependencies

Microsoft Software Shadow Copy Provider can't start, if the Remote Procedure Call (RPC) service is disabled or not available.

Restore Default Startup Configuration for Microsoft Software Shadow Copy Provider

2. Save the Win8_swprv_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

The swprv service is using the swprv.dll file that is located in the %WinDir%\System32 folder. If the file is corrupted or deleted, you can put it back in there.
