Log:
[WINLOGON]
- CreateUserEnvironment: if user impersonation fails, just fail the call.
- SetDefaultLanguage: Use the *correct* HKEY_CURRENT_USER key to retrieve the lang., that
is, first impersonate the user, then, call RegOpenCurrentUser. We do that because
otherwise calling RegOpenKey(Ex) for HKEY_CURRENT_USER just uses the process cached value
of HKEY_CURRENT_USER, which does not change *even if* one impersonates an user.
[MSGINA]
- Correctly impersonate the user when opening & initializing the shutdown dialog (in
the same way as winlogon does), i.e. call ImpersonateLoggedOnUser and use
RegOpenCurrentUser.
- Fill few (but not all) code holes in WlxScreenSaverNotify.
