how to reinstall trial version software after trial period expires ?

How to clean computer to reinstall trial software? this is the question one of my friend asked when the trial period of one of the software expired, because re-installing them again never works as most software's covertly changes or enters some of the registry entries or file system which make them unusable after the trial period, if you don't know places to change or modify then only way to use the software again is re-installing the operating system...

though changing date the hack worked well until few years this is the obsolete method as many software vendors dont fall into this kinda trick anymore but there are few hacks which works but depends

Keep track of changes using Process Monitor
One way is to monitor the changes in the system registry and file system by using a real time monitor program such as process monitor while installing the application so that we can keep track of all the changes done by the application while installing the app by this way we can delete, change or remove the changes after uninstalling the application so that re-install next time application thinks it as the first time install on the system..


but tracking all the changes the keys modified or added changes in file system is one hell of a daunting task but most of the times it works with almost all the applications.

Revo Uninstaller

This is the third party application to uninstall the install apps on the computer it is said that some application uninstalled with revo uninstaller qualifies to re-install agenda though i tried on few applications without any success


and finally some software are very cleverly designed such that it cannot be caught by any monitoring or reverse engineering tool but bottom line all the software can be hacked with quite a time spent on it.

Note: Hacking should be for fun not to steal the software, stealing the softwares directly hurts the industry and people and their families who depend on it, so guys try to purchase the software if it really serves your purpose.
