Extend Windows 7 trial from 30 to 120 days

Hello Friends, you all probably know that we can install windows 7 without any serial key and use this for 30 days. But i have something extra for you, by just doing few steps you can extend this for further 30 days and you can do this 4 times that means 120 days without any key.

The basic way this works is that at the end of the 30 days, you’ll need to run a small command and reboot your computer, at which point you’ll have 30 more days, up to a maximum of 120 days. This trick should work regardless of where you got your copy of Windows 7 from.

How to Extend windows 7 trial by 30 days?
The first thing you have to do is to check how many days are left in your trial period. You can do this by right-clicking My Computer and selecting Properties as shown below:

how to extend windows 7 trial to 120 days
Extend windows trial
At the bottom of this window you’ll see how many days are left to activate (29 in my case since I installed this box yesterday).
Activate windows 7 after 29 days
Activate windows 7
 Now to actually perform the hack that will extend the trial mode, you’ll want to find Command Prompt in the start menu (or search for it), and then right-click on it and choose Run as administrator. (very important)
Run as windows administrator
Run as Administrator on windows 7
 Next you’ll simply type in this command:
slmgr -rearm
Command to extend trial for 120 days
Command to extend trial
Within a few seconds you’ll normally see this dialog show up, saying that the command has completed successfully, at which point you’ll want to reboot.
command executed successfully
Extended trial successfully
 Checking the system properties again shows that I now have 30 days left to activate.
trail has been successfully extended
Confirm that trial has been extended
  Of course you’d normally want to do this near the end, probably on the last day before activation. I’m pretty sure that you can even perform this trick after the 30-day trial expires, although I’m not certain yet.

I hope you all liked this... If you have any queries ask me in form of comments..
