I own a oem version of original xp pro (without any sp) and using nlite , I Slipstreamed with sp3 . after that I try to install and it go through without any problem . I found something strange when I install using the original xp pro (without sp) first then run the sp3 standalone update . it give me error said that I need to at least install SP1 before can install SP3 . so is my Slipstreamed XP SP0 + SP3 is success or not ?
