Volume Shadow Copy (VSS) Service Defaults in Windows 8

Manages and implements Volume Shadow Copies used for backup and other purposes. If this service is stopped, shadow copies will be unavailable for backup and the backup may fail. If this service is disabled, any services that explicitly depend on it will fail to start.

Default Settings

Startup type:Manual
Display name:Volume Shadow Copy
Service name:VSS
Service type:own
Error control:normal
Object:LocalSystem
Path:%SystemRoot%\system32\vssvc.exe
Registry key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS

Default Behavior

The Volume Shadow Copy 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 Volume Shadow Copy service is started, it runs as LocalSystem in its own process of vssvc.exe. If Volume Shadow Copy 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 VSS service hasn't been started.

Dependencies

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

Restore Default Startup Configuration for Volume Shadow Copy

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_VSS_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The VSS service is using the vssvc.exe file that is located in the %WinDir%\system32 folder. If the file is corrupted or deleted, you can put it back in there.
