[PATCH 0/1] MR8046: win32u: Don't load the display drivers in service processes.

[Rémi Bernon]

In service processes, `get_desktop_window` only creates a fake window
owned by the first calling thread, with only a handle and no client-side
object.

Before 9d6455f91cb7a7d166d5c4708d528b43a63eb4d7 `get_window_thread` was
returning an error (called from `send_message` > `process_message`) in
that case, as client-side object is missing.

After the commit, we only check handle existence and we now return
success and then try to send/process the desktop window message, waiting
for explorer startup which never happens.

Fixes: 9d6455f91cb7a7d166d5c4708d528b43a63eb4d7
