Hi guys, First of all, a big thanks to nuhi for the creation of such great tools... I've made a lot of "lite" copies of XP using nlite and now that I want to switch to Vista, I naturally want to lighten it up as well. However, after reading a few posts on this forum, a lot of things are confusing me and I'd like to ask a few things to some of you who have been using this wonderful program for some time now. So here it is. I have had a copy of of Vista business (non SP1) with my Dell laptop. If I understood well, I have to integrate the SP1 before removing anything. Right? So I integrate the SP1 and create a new ISO. Should I "rebuild" the archive? Should I hit the Apply button? (I have read I should only press Apply if I have a copy of Vista Ultimate, is that right?). Also, I've heard it can take quite some time. How much time roughly? Once this new SP1 ISO is made, I can start removing things from it (as I used to do with nlite), right? Thanks in advance for your help.
