Are you always trying to improve the performance of your PC? This piece of software isn’t for the average user, but if you’re feeling adventurous, I recommend you try it.

Vlite removes unnecessary elements from the Windows Vista install. Chose what you don’t want to include and complile an ISO to burn to DVD.
I have used Vlite successfully on my desktop. Visit the site and everything is pretty self explanatory. I contemplated writing a step-by-step guide. Then I figured, if you can’t work out how to do this — you probably shouldn’t try it.
Let me know how it goes for you.
