I am running a school lab. We have IBM computers with Windows XP SP2 on them. We run a program called Deep Freeze to prevent students from changing the settings of the computers. The issue is that windows keeps updating. It restarts the computers as vit is supposed to, but it does it while my students are working on them. We do have the automatic updates set to update at a specific time each week. I am at a loss toexplain why the computers are constantly updating. Does anyone have a suggestion?
