Well, one thing to remember.... Most members of the of the nLite forum don't really know much except about nLite (no offense to yall). Most people of the Unattended forum generalize in what they know (Unattended,Applications,nLite, other member apps). Rule of thumb, if it concerns nLite (bugs or errors) then post in the nLite forum. Otherwise, it's probally better to post in the Unattended forum (since I will most likely see it. All thsoe bug reports sort of cloud the nLite forum) And yes, UPDATE.EXE is the actual program that does everything in the service pack. It does the slipstreaming or the general installing on a system.
