Installation and Activation
Evaluating Windows Server 2008 software does not require product activation or entering a product key. Any edition of Windows Server 2008 may be installed without activation and evaluated for an initial 60 days.
If you need more time to evaluate Windows Server 2008, the 60 day evaluation period may be reset (or re-armed) three times, extending the original 60 day evaluation period by up to 180 days for a total possible evaluation time of 240 days. After this time, you will need to uninstall the software or upgrade to a fully-licensed version of Windows Server 2008.
Note: If you are evaluating and testing Windows Server 2008 and plan to install the software on your primary machine, it is recommended that you back up your existing data prior to installation.
