An application can call the
GetProcessWindowStation function to retrieve a handle of its assigned window station. The security
attributes of the window station can be retrieved and set by using this handle in
calls to the
GetUserObjectSecurity and
SetUserObjectSecurity functions. An application can use the
GetUserObjectInformation and
SetUserObjectInformation functions to get and set information about a window-station object. For more
information on window-station objects, see
Window Stations and Desktops.
