How to reset the trial period of software to use it lifetime?

First, uninstall the software and follow the steps.

After uninstalling

software, OpenRUN

(Windows key + R) and type Regedit and hit

Enter. 

Now Registry Editor Window will appear and

here navigate to 

HKEY_LOCAL_MA CHINE \ SOFTWARE \ 

Your Software name from left

a pane of this window. 

If you find any Key name

with your software name then just Delete that Key.

Similarly, navigate

anything with your Software's
