When you are trying to change the “Display Properties" on Desktop sometimes you can view only "Themes" or few “tabs”. The other tabs like "Desktop", "Screen saver", "appearance" and "Settings are may missing. What could be the problem?The most likely cause of this is malware utilizing Group Policy Objects which enforces policies for system settings and/or user account(s) settings.
