Activating Windows 8 from the Command Line

Discusses how to activate Windows 8 from the Command line.

I seem to be being repeatedly asked the same question for the Windows 8 recently - How do I enter my product key and activate? For some reason the Activate tool doesn’t seem to give the option to change your Product Key for some editions. Fortunately, there’s an easy way to achieve it from the command line.

Start a CMD.EXE session - not forgetting to
run it as Administrator - and use these commands:

First, set your product key:

slmgr /ipk

...and then Activate:

slmgr.vbs -ato

It seems to be an issue for some volume license versions for example.

Anyways, hope the above helps. Anything to add - you can talk about this entry
here at EverythingUC.
