My Win XP laptop has screensaver configuration enforced by a company wide domain settings. It turns on after 15 mins and locks the screen. This is very annoying when I want to watch a movie at home, because I've to move the mouse every 15 minutes to prevent locking the screen. Not even a media player setting to disable the screensaver helps here.
Is it possible to "hack" these settings somehow and turn the screensaver off when I need to?
