When you Get on-line:
Control Panel -> System And Maintenance -> Windows Update -> Check for updates
That will check the M$ database against your Windows and list every update that is available for your machine.

Then go here:

Lists most, if not all, of the performance tweaks that you can do to Vista.
Set it up to work the way you want it to.
