Extend Windows Vista Trial Period from 30 Days to 120 Days




As we all know Microsoft decided to allow Vista users to enjoy Vista for 30 days trial period without activating it or entering Product key. Its really a good thinking and it helps ppl to test Vista without purchasing it.

But do you know that there is a trick to extend this 30 days trial period to 120 days? Yep, you heard it right. You can enjoy Windows Vista for 4 months without purchasing it and its 100% LEGAL.

To extend your Vista trial period follow these simple steps:

1. Click on “Start button -> All Programs -> Accessories“. Right-click on “Command Prompt” and select “Run As Administrator“. If you are prompted to enter password, enter the password and continue. You can also open Command Prompt in Administrator mode by typing “cmd” in Startmenu Search box and press “Ctrl+Shift+Enter“.

2. Now provide following command:

slmgr -rearm

3. You’ll be prompted to restart Windows, restart it and your Vista trial period will be reset to 30 days again.

NOTE: So if you want to enjoy exact 120 days, then give above mentioned command on the 30th day when your trial period is going to end. The command works only 3 times, thats why its limited to only 120 days. You can check the Trial period by going to My Computer Properties.

  1. How do I get a 30 day trial to start using Vista? Thanks very much.
    I have seen your work at DA, winmatrix etc. and like it very much. Very artistic and functional. I am waiting to use VistaVG. Thanks again Wade

  2. Thanks but there is no legal download link for Vista trial. You can ask some one to give you a Vista disc and then you can install it wihtout entering the serial key. ;)

  3. Thanks, guess I will work on changing/improving my XP for now, till I find a disc for a trial run. Thanks to this site I’ll enjoy working with both. Wade

  7. ^^ Its not a general Vista setup. Its a virtual image which can be run to test Vista. It can’t be used as a fully running primary OS.

  8. Excuseme, I have windows xp,a nd I just want to try out the trial for Vista.
    Is it safe for me to upgrade for the free trial?
    My computer did not come with an Xp installation Cd.
    And when the trial ends, can I still have Windows Xp back?

  9. ^^ Nope. afaik you'll not be able to go back to XP, so its better to install Vista trial on other partition.
