We have been using Deep Freeze for almost a year now, and I would say this is the BEST product that has ever come along for anyone who administers publicly accessible computers. In the college environment, we want students to have the ability to install software that comes with textbooks, download applications, and explore the uses of the computer fully. With other products we tried, that was a hassle-- students lost the ability to right-click on their files, applications often conflicted or just plain didn't run. But with Deep Freeze all of those hassles of fighting with lab PCs are gone. The computer *always* remains the way you set it up with a simple reboot. Believe me--you want Deep Freeze in your labs!
