Changing paths of system directories

[chessonly]

In nlite there was a n option to change the path of directories like - program files, documents and settings. As it happens vlite doesn't have this option .

Can someone tell me the 'manual' of doing this ? By this I mean I want to create a vista.iso in which the path of program files/userprofile is custom . I want that the path of the directory "program files" is by default d:\program files , instead of c:\program files .

Yes I know this can be done after installation by playing in the registry . But I want a iso that does this by default. I googled but couldn't find anything useful

Guide please

Edit:

Ok I googled some more. It seems what I have to do is create this file - autounattend.xml , put the relevant path information in it. and then copy the file to a pendrive/cd . right ?
