I need a REALLY reliable software that can shutdown xp systems automatically everyday at a certain time. I prefer to use MS utilities but can't find one. I dont want the BIOS to crash the system and do all kinds of damage to the platform. It needs to be as minut as possible and run in the background and not be considered a virus by AV or antispyware programs. (A savvy user may delete it in an attempt to help). Any Ideas?!?!?
