title: Reset Windows Activation/Remove license key
body: <p>I'm having a hard time finding and answer to this. If I had to hypotheitcally remove the Windows license key from a VM that's been specifically setup for a partner, and it needs to be removed before the VM is handed over, how would I go about doing this? Naturally the built-in 30 day grace period has expired and I'm using an MSDN license key, but I need to remove the key before handing the VM off. The recipient can input their own license key. e.g. how do I reset the Activation Key Wizard's nagging?</p>
