Many programs offer trial periods that allow you to use the software at no cost for a predetermined amount of time. Once the trial period is over, you can no longer use the software for free. To continue to use the program, you must either pay for a subscription or use one of many methods to reset the clock on the trial software. Once the clock is reset, you may continue to use the software for free. Not all methods will work with every program, so try each method to see which one works for the program you wish to keep.
Uninstall the program and reinstall it. This is basic method used to keep a program running after its trial period has expired, but it will not work will all software. Many software engineers program trial software to expire at the end of a given time and reinstalling the software will not restart the clock.
Adjust the date in the date/time settings on your computer to a date previous to that of the installation date of the software. For instance, if you installed the program on June 14th, change the date on your computer to June 13th or before.
Install application-monitoring software that keeps track of system changes that occur during software installation. Use the monitoring software to delete the data related to the expiration of the trial software.
Back up your computer's registry before you install the trial software. Once the software's trial period expires, restore your computer's registry. This method should only be used if you are experienced with computers and with making changes to the registry. If you do not know how to edit or manage the registry, do not use this method.
Reinstall Windows. This method will erase all data from your computer's hard drive, including all personal data such as pictures and documents. Back up all of your computer files and reinstall Windows. Reinstall the trial software and you will be able to use it again. You must reinstall Windows every time the trial period ends if you use this method.
