Wow I'm blown away by these nay sayers. Yes there certainly
are modifications you can make to certain keys in the
registry that will greatly reduce your shutdown times. The
biggest culprit of long shut down times are applications
that are set to clear pagefile when XP shuts down. I've
take computers that shut down in 2 to 3 minutes and get
them to shut down in 15-30 seconds. Here is one valuable
resource that shows how and what you can modify to speed up
your shut down. In the example given you will see a value
of 20,000 as the default value. This is, in fact 20
seconds. Absolutely a life time in computing terms. I have
mine set to 500 which is 1/2 second. Now I certainly don't
advocate that drastic a drop. I have it set that way as I
know my system is safe with this setting. For you I would
start with say 5000 which is 5 seconds. A savings of 15
seconds from the default and ample time for XP to do what
is needed. There are other values like HungAppTimeout etc.
that you can also modify. Why not join the site that I
linked to and then look for me, The Unknown P and I will be
delighted to help you. Contrary to what the other posts say
you can vastly improve shutdown times with simple registry
tweaks.
