That what i was hoping for...Yes you can.
Service Pack 1 is a prerequisite for installing Service Pack 2. Please make sure that your system is running Service Pack 1 before you install Service Pack 2.
Yes a nice sense of satisfaction of adding an extra 30 to 60minutes to do a fresh install just waiting for Sp1 to install...Ahh suck it up. You get a nice sense of satisfaction when you install a service pack anyway so now you get to experience it twice.
I guess there are things in SP1 that SP2 requires before it can install. They won't be in Vista SP0 so SP1 is needed to let SP2 install.Well I never....
That a bit pants really, what happened to the "update to the latest in one hit" days?
