Normal Shutdowns show up as Disruptive Shutdowns

Ever since I went to SP2 for vista x64, any time I shut my computer down it is interpreted as a disruptive shutdown.
User Profile Service and WLan AutoConfig seem to be the only events that precede the shutdown in event viewer.

Here are the details from the log:

User Profiler Service-
1 user registry handles leaked from \Registry\User\S-1-5-21-2330477370-1267348839-2860818693-1000_Classes:
Process 1620 (\Device\HarddiskVolume1\windows\System32\spoolsv.exe) has opened key \REGISTRY\USER\S-1-5-21-2330477370-1267348839-2860818693-1000_CLASSES\Local Settings\Software\Microsoft\Windows\Shell\MuiCache

WLan AutoConfig-
WLAN AutoConfig service has successfully stopped.

What is causing this? Any ideas on how to fix the problem? I really don't like the idea of messing up my registry every time I shutdown.

spoolsv is your print spooler it controls all your printer services and it looks like it isnt shutting down properly.

have you tried ending the process first then shutting down? Just to confirm this is the actual issue?

sorry if you know how to do this ill talk you through it just incase

hold down ctrl/alt then hit delete once

select task manager

select the processes tab

look for spoolsv.exe then highlight it , click end process then confirm in the next box

then shut down (shut down quickly as this process has a habit of turning itself back on )

yuo may also have to stop print spooler in task manager first but we'll try this one for now

Thanks for the reply. I'll give that a shot and post back.

I couldn't see the service in task manager, but stopping it in Services.msc allowed an old printer to be deleted and that seems to have solved the problem. thanks!
