John, I agree with your point about the virtual system, though. After doing an nlite process, I do a test install on my laptop system using MS VPC. Good as far as it goes, but of course, you can't test driver add-ins. I think I'm simply going to abandon the XP SP2 MCE install. MCE installs have always been problematic, even using the MS CDs. I don't really use MCE anyway, and I also have an XP SP 1 license with 10 installs. (from a friend who used to be an MS Action Pack Subscriber.) So in 2-3 days, when I have the time, I'm going to repeat this process, but using the XP SP 1 source, and I'll add in SP 2. Also, it occurred to me since I'm going to install SP3 anway, I don't need to bother with Ryan VM's post SP2 hotfix pack. I can't slipstream SP3 in with nlite, because I have to install an MS hotfix that applies only for AMD Athlon (32 bit) processors before you can install SP3. Once I apply that hotfix, I will install SP3. I've already gone through that process, and it is necessary. Slipstreaming in SP3 directly results in a Windows install that never actually loads up. (The things you find out the hard way.) What do you think? Is it possible to slipsteam just a SP with post-SP hotfixes? That would be so cool. I just want to tell you that I really appreciate the help. I think that nlite is a great tool. I found somthing similar called Office Integrator, but nothing similar for Intuit Quicken or Adobe CS 3. At some point later this year, I will build some new 64-bit systems and move to Windows 7, and no way would I do that process without nlite! Thanks for the tip about that Explorer-Launch bug. x509
