Yes, it's as safe now as it was the day it launched. The only people who had problems brought it on themselves by buying a Compaq system. It was HP's fault in the end anyway, not Microsoft's.
Service packs should ALWAYS be downloaded within a week of being released unless there is a good reason to hold off, such as Compaq owners with AMD CPUs had in this case. If you are not among the affected systems, you should download service packs sooner rather than later.
My daughter just brought a game but it requires sp3.I never downloaded sp3 because of initial reports of problems.Is it safe to download sp3 now?We have a 2.8 ghz pentium 4,running xp home.
