Wird mit dem SP2 von windows xp mit installiert. Ist für manche Rechner fatal, da es die Taskleiste einfriert. Entweder im Task Manager beenden oder einfach unter Windows/System 32 löschen.

Sie lässt sich unter Win7 nur umbenennen oder löschen wenn der User oder Administrator sie vorher in besizt nimmt und sich danach auch noch die Zugriffsrechte gibt. das umbenennen hat aber auf meinem System keine Änderung gebracht.
