The best way is to put a deep freeze on your computer. That way the trial can never keep up with the usaged. Every restart, trail starts back over.

You cant do like that. they will be having some different settings. if the trail period is expired means then you can reinstall that software. (For some software you cant reinstall , if u reinstall also it will say like trial period expired).
