Most of the time I use Windows 2008 products for video recordings and customer site demonstrations. During this period I use TechNet subscription materials for this purpose. Once issue I have been facing is when I want to do another demo after few weeks time the VPC cannot be used do the trial period of the product has been expired! Registering the demonstration purpose operating systems frequently is not an easy option either (Even though I create a set of VPC like that once)

With Windows 2008 you’re getting trial period of 30 days. But if you’re smart enough now there is  way to extend that period for 180 or more. This is really valuable because that means we can keep the vpc’s running properly under trail period for nearly 6 months! (For me that is more than enough!) Good news is this trial extend work around is working for Vista and Windows 7 as well. ok so let’s get start how to extend the trial period.

What we have to do is run a script in the windows\system32 folder called slmgr.vbs

  1. Bring up a Command Prompt.
  2. Type slmgr.vbs –rearm, and press ENTER.
  3. Restart the computer.

You computer has now extended the evaluation period 60 days!  You can run the same command in the same system for 3 times up giving you an activation-free trial period of a total of 240 days!

To find out how many days remain in the trial period you can use the following command.

  1. Type slmgr.vbs -dli, and the current status of the evaluation period is displayed.

Be curious and check out additional commands available in the slmgr.vbs
