If it’s your home computer and your account has administrative rights then you should be able to change any of the settings you like. This may be to avoid having a novice user change a setting or video driver and causing a problem that will involve having to send someone over to fix it.

Many times on networked computers in a business environment you will not be able to make any changes to your display settings if the administrators have set policies that don’t allow you to do so. You may encounter problems trying to change your display settings if you have a certain policy set to prevent you from doing so. If you want to restore access to Control Panel, just change the NoControlPanel value from 1 back to 0.The Display Control Panel applet is used to change things such as background wallpaper, screen colors and screen resolution. After rebooting you’ll be unable to open Control Panel.
