Hi,, apart from my Windows 7 i have one more computer at home that is XP. At my home there are 4 kids who use to play games and surf internet for a long time in a day. They spend almost 8 hours of the day infront of computer and don't concentrate on their studies. So i am here to get about some suggestion regarding the way i can restrict some time limit for the kids to spend on computer. Do you guys suggest me some way ? Thanks for your help.
