The default context for VSS shadow copies is VSS_CTX_BACKUP.
Windows XP: The only supported context is the default context, VSS_CTX_BACKUP. Therefore, calling SetContext under Windows XP returns E_NOTIMPL.
For more information about how the context that is set by SetContext affects how a shadow copy is created and managed, see Implementation Details for Creating Shadow Copies.
For a complete discussion of the permitted shadow copy contexts, see _VSS_SNAPSHOT_CONTEXT and _VSS_VOLUME_SNAPSHOT_ATTRIBUTES.
