New install of Windows 7 - Out of box experience

Hello all,
I have just sold my Laptop and have reinstalled Windows 7 back on the machine for the new owner. I was just wondering if there was a way of resetting the machine back to the Out Of The Box Experience for the new owner.

Im wanting to do all the updates and software installation now and then "reset" it so the new owner can open it from fresh etc.

Ive had a good Google but couldn't find anything.

Has anyone got any ideas?

Regards
