Hi,
I'm struggling with a similar problem, exept with me it seems to be
the "sysmain" or "superfetch" service. Stopping this service (or
disabling it in services.mcs) stops the CPU spikes.
I just want to know whether or not this service is critical for my PC
and of there is some kind of update available to fix this problem.
Thanking you in advance...

Seeing brief spikes are normal. Blindly stopping any system service is
foolish. Vista does it's thing in a certain way. Unless you know what
each application, applet, service, process or script does, don't mess
with it.
As I've suggested several times download and use Autoruns. It is a
nifty free little application that gives a great deal of information
about what your system is doing. Study what's shown under the various
tabs and you'll learn much more about Vista's internal workings than
you ever will from any newsgroup or book.
One common reason for a slow or sluggish system is Windows can if you
let it start up all kinds of crap every time you boot. What a lot of
people don't known is things can be started in different ways form
uncommon locations in your Registry. These can eat away at system
resources and make you system slower than it needs to be robbing your
system of memory it could use for something else.
One thing AUTORUNS does is let you explorer what's happening. For
example if you click on it's Logon tab it shows what Windows is going
to start when you boot.
While many are aware of the Registry Key
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
They may not know things can also fire up from these keys:
HKLM\Software\Policies\Microsoft\Windows\System\Scripts\Startup
HKCU\Software\Policies\Microsoft\Windows\System\Scripts\Logon
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\Shell
And several others using even more Registry hideouts like the common
Adobe Gamma Loader getting fired up from:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup. Note
unlike the previous this one isn't in the Registry.
That's just scratching the surface. If you move on to the Explorer tab
you see HKLM\SOFTWARE\Classes\Protocols\Handler and all the internal
crap Vista starts off plus a dozen more keys that each in turn fire up
a lot more things, sometimes junk you don't need.
Then if you really want to get curious check the Services tab and on a
average system you'll see around a hundred more listings. Using this
in combination with typing in 'services' from the Start Orb and
carefully see what happens when you change SOME services from
automatic, to manual or stop. Of course you shouldn't haphazardly mess
around, but this is one way to streamline what your system is doing
and turn off things you don't need.
