15 minutes to shut down

[Guest]

About one month ago my computer started to shut down slowly. I am able to get
to the "shutting down" screen quickly, but then the computer hangs for 15
minutes or so. I am not sure how to fix this. One really odd thing that I
noticed is last week I did a windows update and downloaded some patch for
Windows Media Player. The next several times I shut down it was very quick.
Then as suddenly as it was fixed it was back to taking 15 minutes to shut
down. Any suggestions? I checked my event log, but don't know what to do with
the information it gave me.

Ok, I figured out what was the problem. I generated a "system health report"
and found out that the Microsoft ISATAP Adaptor had some problems. I couldn't
find out what it did so I disabled it (instead of uninstalling it). I don't
see any ill effects on my computer and it shuts down in a normal amount of
time now!!

Ok. One more thing. After I disabled the driver in the device manager I got
some strange error messages in IE about add ons being disabled. I decided
just to uninstall the driver and my computer seems to be error free. At least
i'm not experiencing the errors I had when it was only disabled.

Not a suggestion for your particular problem, more an explanation:

When you tell Windows to shutdown it first makes sure other
applications aren't "busy" which is different than simply running. If
some application is hanging on to a Registry handle Windows will wait
till the stubborn application lets go of it. The problem is the wait
can be very long and usually for no reason. This will suspend the
normal shutdown sequence since Windows is tricked into thinking some
service (application) isn't quite yet finished doing something.

If you are game to messing with your Registry you can use regedit to
find the string: 'WaitToKillServiceTimeout'. It by default should read
20000 which means Vista is going to wait 20 seconds before it starts
to "kill" all running services, (assuming nothing is hung up) which is
like you manually doing that from Task Manager.

You can reduce this value... doing so will make Vista force a shutdown
quicker. Just Don't get carried away. If you try. of course make a
Restore Point first. I would suggest a number between 12000 to 15000
is better if you really want to push it try 10000 but no lower. Should
shave a few seconds off you shutdown time.

If you want a more technical answer check this out:

Any of the things mentioned plus others can cause Windows to sputter
during the shutdown process which isn't just a single step but in
reality a whole series of events.
