Guys, I really want to thank all your support on this matter. Before I begin, i must quote Guns ´n Roses Civil War: "What we´ve got here is failure to communicate..." I can only blame that on my rough knowledge of English. So sorry for that too. I must make myself clear on some topics: 1) I´ve NEVER used HFSLIP or RyanVM. As I said in the first post, only have used nLite and I´m doing some research on these two tools before using it for the first time. 2) The sentence that got fdv to become so upset, "If that´s true, I guess my days with HFSLIP are over even before the beginning...", never was meant as a disappointment with the tool, because I´ve never used it, like I said above. Let´s explain what happened: bhlpt is right in his understanding of what I´m doing with my install disk. I´ve been applying SP3 and all hotfixes after that using the /integrate switch - so, using tommyp terminology, i guess SP3 was slipstreamed and all hotfixes were just integrated (so they are all residing in the svcfolder inside I386). I´ve wrote the dreaded sentence because fdv said that to undo that (so i could get back to a install disk only with SP3, i would have to do more than deleting the svcpack folder and replacing svcpack.inf (He talked about some dlls being changed and other stuff). Then i realised i don´t have time/patience/expertise to do that and told him i would not use the tool, but somehow he got that as a harsh critic. Believe me, it was not. tommyp also got it wrong, so I guess that´s my bad - Sorry again for that, tommyp and fdv. If fvd really is serious, he will not come back here to read this, so if somebody could explain that to him, I will be very grateful. Now I´ve found an easy solution: I have an original key, so i´ve donwloaded a fresh new XP SP3 from a torrent site (don´t worry, i´ve done a sha1 check). I´m working on this iso from now on. I just have one more question: what method do you recommend for me to download and keep only the needed hotfixes (because as bphlpt said, some hotfixes become superseded by new ones). If you could indicate some tool that download them and can do that kind of work, it will be very nice. As always, I want to thank all support and leave my sincere apologies to the admins. Thank you all!
