Starting Windows Vista, Microsoft lets you extend your grace period through a process known as ‘rearming’. Its awesome! The downside is that the modern.ie virtual machines use evaluation versions of Microsoft Windows and are therefore the license expires.

Modern.ie was created by Microsoft and allows you to use Windows virtual machines without purchasing Windows licenses. If you are a tester and do not know about modern.ie, I recommend reading our post on cross browser testing tools. You can check how many days are left in your trial period, by running slmgr.vbs -dli in the Command Prompt.This post is meant for testers who use modern.ie to run cross browser tests.If you want to enjoy exact 120 days, run above mentioned command on the last day when your Windows trial period is going to expire. Restart your computer and you can use the trial version for another 90 days for free.After a couple of seconds it will show you the message window that the command has completed successfully.In Windows 10 or 8.1, use slmgr.vbs /rearm instead.
