Windows Server 2008 Server Core has no GUI. So how do you do the Product Activation for Server Core? How do you check if activation was successful? This post tells all.

To activate Windows:

cscript C:WindowsSystem32slmgr.vbs -ato

To get lots of useful information about the activation:

cscript C:WindowsSystem32slmgr.vbs -dlv

To find out how much time you’ve got (to activate, of course):

cscript C:WindowsSystem32slmgr.vbs -xpr

Output displayed will tell you when the grace period will end.

Microsoft (R) Windows Script Host Version 5.7

Initial grace period ends 4/20/2008 11:23:28 PM

If you are already activated, -xpr switch will tell you that, too

Welcome to the dark side.
