Hit2k.com – DeepFreeze Server Enterprise Enough powerful utility that was very popular with users such as I like, but unfortunately I chose the other product, though, and thought about it. In any case, the program will help users to protect the operating system kernel, as well as all configuration files on your computer from unwanted changes, as you can each time to restore the original system settings after rebooting the computer, download Deep Freeze can be lower.
From minus is the absence of Russian support, I think the common user will not understand very easily. quite convenient interface, not overloaded with graphics as a whole does not cause negative. In general, such a large number of programs, I personally chose instead Deep Freeze analogue Sandboxie and quite happy, but we have a lot to you and everyone has different tastes, so I hope you will come in handy utility.
