When it comes to shutdown of windows vista it takes even more time as compared to windows xp. Default shutdown time of vista is about 20 seconds to kill all the services and user programs that are currently running.

But don’t worry as you can simply decrease the time required by windows vista to shutdown irrespective of any edition of vista you are using , by a simple registry trick you can decrease the shutdown time to a great extent.

So the only thing you have to do is to open notepad , 

Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl]

"WaitToKillServiceTimeout"="20000"

copy everything in the blockquotes above  and paste them in a notepad file and then save as .reg file. Not only this you have to change the WaitToKillServiceTimeout value 20000 to 5000 or any other value but don’t set the value less than 5000.(5000 = 5 seconds).
