Unregisterwsswriter: Stsadm operation (Windows SharePoint Services)

Applies To: Windows SharePoint Services 3.0


Topic Last Modified: 2007-03-29

Operation name: Unregisterwsswriter


Disables the Windows SharePoint Services VSS Writer service (known as WSS Writer service) on any front-end Web server.

WSS writer is a service that conforms to the standard Volume Shadow Copy Service (VSS) writer interface. A third-party backup or restoration program can interact with the VSS system service to backup or restore Windows SharePoint Services 3.0-related components. Because the VSS interface is public, software vendors can handle backup and restoration of Windows SharePoint Services 3.0 components in a standard way rather than writing code on a case-by-case basis.

In the latest version of Microsoft Windows Server 2003, there is no functionality included with the product that an end user can use to take advantage of the WSS writer service, or any other writer service such as the SQL writer. An end user will need to buy a third-party backup or restoration program to gain this functionality.


The unregisterwsswriter operation does not take any parameters.


stsadm -o -unregisterwsswriter
