Modifications made to the settings will be undone, files downloaded from the web will be removed, and other unwanted changes will all be undone when you restart your PC. It puts everything on ice so that no unwanted changes can be performed on your PC. You can enter the freeze mode with a simple click and quit the freeze mode with a simple restart or shut down.
