Extend Windows Vista to 120 Days Without Activation

Posted in Business Software, Site News, Windows

Microsoft Vista

This might be an old news to several geeks, but still, it might be worthwhile posting. Normally, Windows Vista is first installed, it can run on the machine for 30 days without having to enter a product key. After the evaluation period, the user would either need to buy the product, just to get the activation key and retrieve some files off the computer.

However, there is an alternative to extend this 30 days limit to 120 days. According to Dwight Silverman, on Day 31, Windows Vista boots up and shows a warning message informing the user that the version of Vista is “not genuine”. It then opens up the Internet Explorer asking user to purchase an activation key.

To proceed:

  1. Click on the start button and type “Cmd” into the Start Search box.
  2. Press Ctrl-Shift-Enter to open the command prompt.
  3. Type “slmgr -rearm” and hit enter.
  4. Reboot the computer.
  5. Make sure to re-arm the system again 29 or 30 days later.

Note that this feature was built into Vista by Microsoft, and the company has confirmed that extending the evaluation period is not a violation of Vista’s end user agreement.
