[Trace Windows 7 boot/shutdown/hibernate/standby/resume issues]

All of the shutdown time here appears to be because a WMI provider takes forever to shutdown, but the CPU time is all in a thread in the shutdown logonui.exe process (showing you the shutdown status screen). To get anything useful out of this, you're going to need to take a new trace with only the following options:

xbootmgr -trace shutdown -traceflags dispatcher+latency -stackwalk readythread+threadcreate+cswitch+profile -resultPath c:\shutdown_trace

Here is the new trace with the options you specified. The computer took long to shutdown as before, but after I got back on my desktop, there was a notification asking me to Cancel or Finish with a timer of 130 seconds. I clicked "Finish" not knowing what it was, other than assuming it was part of the trace, and my computer rebooted again this time not delaying to shutdown. With that said, I dont know if the Trace data is accurate on that account but here it is.
