Thanks MagicAndre. That's a step in the right direction. I'll do some more research and maybe unplug a couple USB devices i don't use on a regular basis to see if it helps.

Hi MagicAndre - great thread. For the last 6 months, I've been experiencing the following issue at Windows 7 SP1 64bit Enterprise shutdown: - shutdown works fine when done within a couple hours of startup - shutdown takes forever (until ACPI? timeout and forced reboot) if the PC has been on for longer than that. I have captured a good shutdown and a bad shutdown file (etl) with BASE+CSWITCH+DRIVERS+POWER and loaded them up in the GUI but can't make much sense of the information. I think I need your expert help! This was the command I used (from the first post) xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP Good and bad shutdowns are here: https://www.dropbox.com/sh/q3cb7o5tjhnrm9s/hVIwM_tK6c Let me know what you think Thanks
