unfortunately this doesn't work with 99% of software as the software is accounted for using registry keys even if the software is uninstalled a lot of the time they'll cheakily leave the registry keys there so that they know that the trial is expired. sometimes they might even place/alter system files.

if you want to do some snazzy illegal stuff then look up softwarename + crack on google, but i'd just recommend sticking to the free stuff.

if you're a mac os x user just do a search for plist files and find the one that corresponds to the program you want to deregister and use again for trial.
