Toolwiz Time Freeze is a freeware which can create a virtual copy of your system so that you can test out any new software or any configuration changes. If they don’t work out, you can quickly go back to the previous state.

Many of the software that you download from the net may come with Trojans or other side effects that you may not know about. If you are not sure whether the software is from a trusted source, it is better to try it out in a virtualization environment so that any changes made can be easily reverted without any permanent damage.

The program is simple and easy to use. Just install the program and run it. Just click the ‘Start Timefreeze’ button and it will then create a virtual copy of the system while keeping your current system in constant state. The changes made can be undone by simply restarting the computer or you can even save the changes if you want. Apart from it, you can also use it to protect selected files and folders so that they are protected from any Trojan and viruses.

The program is very useful. It is a freeware and works on Windows XP/Vista and Windows 7.
