From Neowin.net & Bink.nu:
Windows XP SP3 is finally here for those that use Windows Update, and here is a direct link to the stand-alone version of SP3 for x86 XP systems (32 bit). Thanks Bink! Neowin reader WindowsNT says: “There won’t be a 64bit version until Windows Server 2003 hits SP3 since they share the same code base.”
Here is an interesting article regarding SP3 performance, ignoring the fact that Vista SP1 is still faster than XP SP2/SP3 users will enjoy a performance boost over SP2. When will people learn that Vista ain’t all bad!
Windows® XP Service Pack 3 (SP3) includes all previously released updates for the operating system. This update also includes a small number of new functionalities, which do not significantly change customers’ experience with the operating system.
