Found this message thread via Google and it saved the day for me. Just thought I'd contribute to the accumulating info/knowledge on this problem. Today Win-XP wouldn't boot into ANY mode - hanging at MUP.SYS as described by others. I unplugged my USB optical mouse (Microsoft mouse by the way) and USB CompactFlash card reader. Win started up fine. I immediately shut it down again, plugged my mouse back in and re-started. All is now well. We'll see if the problem re-appears. Note that in the past 3 weeks I: a) changed from a regular mouse to the USB optical mouse. b) accepted a USB update from the Microsoft Windows Update web site. --jeff r--
