Hello, I just joined the forum. I heard Window XP SP3 is going to be out pretty soon. So, I wanted to prepare my installation using this fantastic software "nlite". What I want to do is to remove "Security Center" and "Automatic Update" at least. So, I intergrated SP3 to Windows XP OEM (without any SP) by removing these elements, il installed fine, but I see "userenv" error in Event log. What I don't understand is that when I tested some time ago, I also removed "Security Center" and "Automatic Update", and there was no error in Event log, and this installation is even now working in another PC. But, unfortunately, I did not backup the ISO, thinking that the process was easy, and I could reproduce the same ISO. As far as I remember, the difference is, when I made the first test, I removed many other elements as well. Is it possible that "not removing some elements" gives this error?? By the way, when I just integrate SP3 without removing anything, it installs without any error in Eventlog. Does anyone have some clue? How can I remove "Security Center" and "Automatic Update" without having errors in Event log? I would greatly appreciate any suggestions. Thank you in advance.
