Convert Windows 7 from KMS to MAK License Keys

Installed some Windows 7 Professional VM's to find that they had defaulted to KMS licensing.

It was relatively easy to convert from KMS to MAK with the following command lines:

1. Install the product key (replace with your key):
   slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
2. Activate:
   slmgr /ato
3. Display license information:
   slmgr /dli

Thanks to this post for most of the help:
