Well, yesterday I downloaded Windows XP Service Pack 3. I was excited at how much better it would make my computer. I was wrong. My computer, after the installation and not one, but TWO restarts, was around 1/3 of its normal speed. Microsoft, I have to say this to you - YOU SUCK! I'm very disappointed with this Service Pack. I've uninstalled it... computer, surprise surprise is back to normal speed. Is this some sort of scaled-down version of Vista? Overall, I have to warn you - SP3 isn't any good.
