Extend Windows 2008 Evaluation time frame

Remember someone asked me about how to extend Windows 2008 evaluation. This is important as we do not want to reinstall all the hardworked configuration, especially we are doing some R&D or testing.

By default, Windows 2008 will allow you to evaluation for 60 days, and use the following command to evaluate up to 180 days! Thats cool - all the research for sure be able to finish within 180 days - unless you want to use it for production :).

To do it?

1. Click Start, run -> CMD.
2. Type slmgr.vbs -dli, and ENTER to check the current evaluation period.
3. Type slmgr.vbs –rearm to reset the evaluation period and then press ENTER.
4. Restart the computer.

Thats it. Want to know more? Microsoft release one KB article about it:
