Windows: avoid timeout of Secure Desktop display by waiting for the user to be really authenticated. Under Windows 10, a user session can be started in the background even before the user has been authenticated and this was causing VeraCrypt to be started before the user has logged in, in turn this was causing Secure Desktop to fail.
