customize vista and xp as per ur requirment

yesterday i gone throgh with a s/w nlite
it is very usefull coz u can customize ur OS as per ur requirement
means u can add drivers, hotfixes, updates and programs etc
and these s.w and drivers ll be installed along with the OS
so need to install all the stuffs after fresh installation
its handy and ready to use
and for vista its vlite
vista in vista u can preload ur driver so that they can run after installation
no error or no compatibility check
njoy!!!
