If you want to utilize this feature, do you first establish an Acronis secure zone? The help is pretty good but I'm unclear about the steps; Secure zone first, begin Try and Decide for a specified time.[days to see if Ccleaner caused trouble] Run your trial program like Ccleaner. If no problems click on keep changes and if trouble = click to return to previous state. Any things to add or correct ssuch as the size of the hard drive for a couple of days having the program run?
