I'm a little bit confused anout the integration of hotfixes with nLite. I use Windows Updates Downloader to download updates, but how do I find out which ones do I need to download? Also how do I know which hotfixes and updates my windows already has? (so I won't download and integrate them). For examle I have a windows xp folder on my computer and I want to make an unattended cd but I also have a folder of 363 updates (600mb) and I don't know which to integrate. And one last question about nLite. If I made an .iso of XP automated installation and integrated some hotfixes, but then I realize that I missed some, what do I do? I mean if after I made an iso file of XP, I download some more hotfixes in the derectory where I have windows updates, and I decide to include these new updates to my XP I built but I don't know which ones I already did include, can I integrate ALL the hotfixes that I have, would it be any different if I integrated just new hotfixes? Thanks for help
