i tested that software years ago, it was pretty good for what it was for. it does what it says its going to do but if you are concerned about lets say av updates or something else that needs to be updated you can schedule a section of the computer to be thawed so it can actually write changes to the computer. same thing if the person using the computer is going to write changes and it actually needs to stay you need to thaw that section of the computer. because as you know once you reboot the computer everything is back to how it was.
i dont know price.
