How to activate Windows 8 Enterprise

Windows 8 Enterprise installs without asking key which is then changed afterwards. Graphical tool won't work. Off to the command line:

1. Get the key! Don't know where. That's up to you! MSDN?
2. Click right key in the left bottom corner of Windows 8 and click with left Command Prompt (Admin). Click Yes.
3. Type the following command: slmgr.vbs /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX . Replace X-letters with your key. (No period in the end of command!) After pushing enter Windows 8 Enterprise is activated! I was a bit surprised since command slmgr.vbs /ato wasn't needed.
