windows 7 key reuse

Hey guys,

I'm selling my 1 year old laptop (laptop 2 in sig), which came with Vista OEM.
I installed windows 7 on it with a key from MSDN. My best friend(the buyer) will format the laptop before he gives it to his sister, so I wanted to know how I can reuse my key for a new pc in the future.

I googled a little bit, but I couldn't find a clear answer. Will I have to call Microsoft or something?

kind regards,
