Switching from KMS to MAK Keys in Windows 7

This may be of interest to those who have installed Windows 7 on a laptop and had the problem above, and hardly ever connect their laptop to your corporate network at all. When using KMS, Windows 7 must talk to the KMS server at least once every 6 months. You can remove this requirement by switching to MAK activation.

Note down the Windows 7 Enterprise MAK key.
  • Follow the instructions above to open a "Command Prompt" window, then type each of these commands, ending each one with the Return key:
    slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
    slmgr /ato
    where the "X"s are replaced with the serial number you just noted down.
  • Close the window by clicking on the "X" in the top right corner of the window.
