What is the difference in performance between full XP (with integrated SP2) and XP (with integrated SP1) updated with SP2?
Answer #1
The full install will install the complete CD like a new/fresh install. There is a possibility that you will loose all your documents and settings doing this.
The update just updates whatever is on your PC to bring it back to default SP2 if that is what was installed initially. e.g if you changed some settings such as disabling the automatic update service and error reporting service ….. these will be returned to enabled. Or, if you removed the shortcut arrow on your desktop icons using a tweaker then the arrow will be returned …….. things like that.

I mean diffrence in performance…
Answer #3
None on performance. It’s just that if you install a non-SP2 you might catch some bugs off the net even before yo manage to update to SP2. It happened at my workplace. It took like a minute of just being connected to the net and had a worm infention.
