Hi All,

The VSS hardware provider API is supported only for Windows 2003 EE/DCE.
The VSS software provider works well under any Windows 2003 version and
Vista, but fails to install in XP SP2.

MSDN says that IVSSSoftwareSnapshotProvider interface is supported under Win
XP too,
but XP headers that come with VSS SDK 7.2 do not contain this interface
definition.

Does Windows XP support custom VSS software providers?
