Hello all, I recall reading a thread here at Wilders from a few years ago, claiming that DeepFreeze did not protect the MBR and was thus inferior to other virtualization solutions. In addition, some googling turned up this page ( http://www.velocityreviews.com/forums/t307362-faronics-deep-freeze-losing-the-security-war.html ), detailing some previous failings of Faronics to fix vulnerabilities in DeepFreeze in a timely fashion, although presumably all is good now. I am curious if anyone has used DeepFreeze lately. I see it is compatible with Windows 7 and 64 bit as well. I gave it a spin on a test machine, and it appeared to work well enough, even if it is a bit simplistic. It also left a .sys device driver on the root of my C: drive, which was visible but restricted from my access. Sloppy of them. Any thoughts on its security, or if it uses disk or ram to cache changes during a given "frozen" session?
