Well, we just got our Deep Freeze package thru BOCES (Thanks for partnering with them). Deep Freeze is fantastic. I don't think Kryptonite could get by Deep Freeze. I loaded Deep Freeze on a machine and told my son (21 yrs old) to go ahead and trash it. He ran 4 seperate Hard Drive destruction/erase programs for a total of 4 1/2 hours. When we rebooted, it was as good as new. He was impressed...and impressing him, impresses me. Thanks again for your efforts.
