Re-registering a Windows 8 install with a new product key

I installed a VM on my machine with an image that was registered to another user. It is easy to add a user profile for yourself as an Administrator and remove the old user, but Windows remains registered to the original user's product key. Use this command from console to replace it with your key...

slui.exe 3

You'll be prompted with a dialog where you can provide the new key.

Say Thanks
