This may have been shared before or not but I have been using this method to test fully functional trial programs before I decide on buying it. I am not promoting piracy in any way. If you feel that a program is useful, you must give credit to the author and buy it. Method: - What tools / software do I need? Deep Freeze - What is Deep Freeze - Search Google - How do I use it? Make sure that your PC is configured to boot frozen before launching the trial software. Use the program all you want. Reboot your PC. Use the program as if its your 1st time launching it.
