When I installed Windows Server 2008 I didn't have the (activation) key. Now that I have it I can't find where to enter it. Anybody know?

Go to Control Panel\System and then under Windows Activation click "Change Product Key".


I know in Vista this is done from the system control panel. I would check there in Server 2008.


There might be an icon down in the tray, or it will prompt you during logon. I don't recall how long it will take to prompt you, or if it takes any time at all.

Try rebooting and logging on.

Right click on Computer and select Properties. Then select Change product key under the Windows activation section.
