Default Behavior

Windows Backup is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Windows Backup service is started, it is running as localSystem in its own process of svchost.exe. If Windows Backup fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the SDRSVC service is not running because of the error.

Dependencies

Windows Backup is unable to start, if the Remote Procedure Call (RPC) service is stopped or disabled.

Restore Default Startup Configuration for Windows Backup

1. Select your Windows 7 edition and service pack, and then click Download.

2. Save the Win7_SDRSVC_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The SDRSVC service is using the SDRSVC.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 7 installation media.
