Most of us are familiar with many softwares that run only for a specified period of time in the trial mode. Once the trial period is expired these softwares stop functioning and demand for a purchase. But today I will show you how you can run the software beyond their trial period. How does this work? Before I tell you how to hack the software and make it run in the trial mode forever, lets understand how this software works When these softwares are installed for the first time, they make an entry into the Windows Registry with the details such as Installed Date and Time, installed path etc. After installation every time you run the software, it compares the current system date and time with the installed date and time. So, with this it can make out whether the trial period is expired or not.
