Thanks for your quick response, appreciate it. I am continuing this discussion of slipstreaming SP3 through nLite and have edited my post to explicitly say that, thanks for the heads-up. There are mixed messages about the ability to slipstream SP3 onto tablet or media center editions of XP. I was hoping to use nLite (one of the best essential programs, IMO) to integrate SP3 into Tablet. If I could use the MSDN stock SP3 disc as the source files in nLite, and integrate the tablet components, I think I could create a SP3 Tablet disc as close to "stock from Microsoft" as possible. If I need to carry out an original post on Tablet SP3 nLite integration on its own, I will. (I think best to err on the side of searching the forums and adding to your post, rather than starting yet another post on nLite SP3 integration and being told to search first)
