Windows Product Key

I have a HP 6735s laptop, came with Vista home pre installed. I have now upgraded to Windows 7. My son has a desktop built by myself, so no brand on it. Can I use the serial that was used when installing the vista to my HP laptop as i recovered it using Keyfinder, as i believe that it will come up saying invalid key as it isnt a HP machine. Or do i use the product key that on the sticker on my laptop. Would i need to call microsoft to enable this key?

Thanks in advance for your help.

both will work, pre-installed is prob a volume key - one on the lap top will have to be manually activated.

I would use the one on the laptop

Not sure if I've understood the above scenario, but your vista (oem) license on your laptop cannot be transferred to the desktop as per the EULA.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
