"I was trying to reduce the number of processes that TSR at startup", why? Were they causing a problem? The term TSR is from DOS/Win 9X, it is not part of the Windows XP world, the paradigm has shifted. I would suggest put everything back to the way it was. My best advice is to leave it alone. Many of those who post on these boards, will disagree with me, but I have several systems that work, others seem always posting about strange/weird problems. At the two large organizations I worked at, all PC's ran a default load with no pruning of start up processes.
