Extend Windows 8 Trial Period for More 90 Days

Hello,
Windows 8 is available free for 90 days, some of my friends using it any every time ask that how we can extend its period. For past few days I was searching solution for this, and today I got it. You can do this with command prompt.

Microsoft selling Windows 8 at very cheap price and proving us up-gradation at very low price. But me and my friends don't wanna purchase it so we I am using this trick. Now you can also use it.

How To Do:

1. First of all open CMD Prompt as an administrator.
2. Now in this type slmgr /rearm and press enter.
3. A popup windows will open and you can see "Command Completed Successfully"
4. Now finally restart your computer and you can see 90 days trial resettled.

Note: You can do above steps every 89th day or your trial period so that you can get another 90 days for free. This trick is based upon Windows 7, In Windows 7 we can do this 4 times, so maybe this would be same in Windows 8.
