Various issues after you restore a system state backup that is saved by using VSS if the "ImagePath" value for a service contains a forward slash (/) in Windows Vista, Windows 7, Windows Server 2008, or Windows Server 2008 R2

Symptoms

Consider the following scenario:
  • A service installs an "ImagePath" value in the registry on a computer that is running one of the following operating systems:
    • Windows Vista
    • Windows Server 2008
    • Windows 7
    • Windows Server 2008 R2
  • The file path in the value uses a forward slash (/) instead of a backslash (\) as the directory delimiter. For example, the file path is %program files%/software/bin/service.exe.
  • You perform a system state backup by using the Volume Shadow Copy Service (VSS).
  • You restore the system state by using the backup.
In this scenario, the restored operating system enters an indeterminate state. Therefore, you may experience some operating system failures. For example, the following failures may occur:

Cause

This issue occurs because of the forward slash (/) that is used as the directory delimiter in a System Image Path registry entry. The VSS System Writer treats a forward slash (/) as an invalid character. This behavior causes the VSS System Writer to stop enumerating the rest of the files that should be included in the VSS System Writer metadata document. Therefore, many files are missing when you restore the system state backup.
