That is the problem unfortunatley. I am in a catch 22. I have tried clean boot many times in the past and have even disabled all the MS items and tried th shutdown. Have tried safe mode with all services and startup items off - this included all the MS services. This did not speed the shutdown at all. Still took a long time. I have booted up with minimal items on and I cant get a full trace for you to look at either. I am at a real loss and have run out of ideas.... Not sure what to do from here.

I ran that command as suggested..........here is the link....thanks It appeared to get both now.... http://sdrv.ms/WzSjNc

No that is all that is recorded. I have done it twice now and I always get the following files. Nil other. shutdown_BASE+CSWITCH+DRIVERS+POWER_1_km_premerge (720Mb) shutdown_BASE+CSWITCH+DRIVERS+POWER_1_um_premerge (7Mb) xbootmgr My screens stays on shutting down for a long time before it shuts down. I used this command to run the shutdown trace... xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP Here is a link to a trace done before the one you have already seen. Not sure if it adds any more information... http://sdrv.ms/15RdWPM Let me know if you want me to try it again.... Thanks....

For past 3 months my PC shuts down very slowly - up to 15mins. All clean boot tests etc are not solving it as yet. I have also tested with all devices disconnected + antivirus and acronis turned off. However when in SAFE mode it shutsdown normally - everthing works fine and fast. My PC is not old an has Windows experience of 7.4. I have recorded a trace for shutdown. However I dont know what I am looking at. The link to the etl files for shutdown trace are in skydrive: http://sdrv.ms/WxHWcK Can anyone help if you have time please...I am at a real loss as to how this can be fixed? Thanks in advance. J
