Tests show that shell windows are per-desktop, not global. Existing tests also show that new desktops from CreateDesktop do not have a shell window set initially. The Default desktop on WinSta0 does, however.
GetShellWindow ought to return an IShellView's window, but we never actually make one of those for the desktop. However, there is a common pattern (used by e.g. GOG Galaxy) of retrieving an unelevated token by duplicating that of the owner of GetShellWindow, so having any window set at all is a step in the right direction.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=148805
Your paranoid android.
