A process automatically establishes a connection to a window station and desktop when it first calls a USER32 or GDI32 function (other than the window station and desktop functions). The system determines the window station to which a process connects according to the following rules:
The window station assigned during this connection process cannot be closed by calling the CloseWindowStation function.
When a process is connecting to a window station, the system searches the process's handle table for inherited handles. The system uses the first window station handle it finds. If you want a child process to connect to a particular inherited window station, you must ensure that only the desired handle is marked inheritable. If a child process inherits multiple window station handles, the results of the window station connection are undefined.
Handles to a window station that the system opens while connecting a process to a window station are not inheritable.
