Reseal Windows Vista.. How to?

Hi,
i am quite sure there is no similar thread.. i searched.. only about xp.. which is different than vista in so many things..
anyway
my question is quite simple and straight forward:

how can i reseal my windows vista?? i bought some1 a laptop as a gift, i added many software and stuff, now i want to reseal it.. to make it look nicer.. anyway.. HOW?? :confused

i searched all over and couldnt really find a place where i can download the executable file to reseal it, or smthn like that... its getting on my nerves now!

thnx anyway for all the help and advices guys.

oh and in case someone wonders what reseal means: re-seal stands for sealing your windows again, it keeps all installed software, and files, but just resets the EULA agreement and user accounts, so basically you get the welcome screen, name your pc and create your username... basically the option to personalize your laptop for real!

thnx a million
Cheers

just to close the thread
i figured it has something to do with sysprep , which is actually it...
you can either do it through cmd or using gui for better results...
u can (under start menu, in the search area) type sysprep , it shows up asking u what u want to do, u choose OOBE (out of box experience) and remove the tick from generalize... and once u rebooot u have the laptop running as if u really just got it out of the box, the whole EULA agreement , creating user and whatnot... and u keep any software u installed...
u can choose other options under dos, like genralize, audit and such, but to each its own options... feel free to explore
if u want to try it under dos make usre u type sysprep when ur under c:\windows\system32\sysprep (if i remember correctly) , and thats basically it
