Toolwiz Time Freeze enables you to temporarily virtualize your PC in order to test new software or try out configuration changes. Once started, Time Freeze will initiate a virtual copy of your system and any changes made can be safely reverted by rebooting the computer.If whatever you were testing worked out well, there is also an option to save the changes to your system instead of undoing them. Toolwiz Time Freeze can also be used to protect selected files and folders from being changed.The program is easy to use and provides a quick and convenient way to test out new stuff on your computer without running the risk of breaking anything.
