For the longest time, Windows XP was the latest, most secure and most feature rich operating system available. It provided tremendous improvements over Windows 98, including hundreds of security patches, a more advanced version of Internet Explorer, native support for 64-bit software and hardware and was free of the aging DOS kernel. However, as time went on, Windows XP began to show its age. That is why Microsoft has been rolling up recent patches, as well as some welcome feature additions, into this Windows XP Service Pack.

It is crucial to always have the latest version of Microsoft's operating systems and service packs. This helps to keep your computer safe, improves stability and adds handy new features. For example, Windows XP Service Pack 1 fixed numerous bugs, streamlined wireless network connectivity and patched some security holes that slipped through the cracks. Service Pack 2 was an even more comprehensive update, introducing Microsoft Internet Explorer 8, a newer Flash player "out of the box" and a powerful new spyware removal tool. Service Pack 3 helped to keep Windows XP fresh even after the release of the more advanced Windows Vista.

Many users still argue that Windows XP, with the Service Pack 3 update, is the fastest and most reliable operating system in the world. Its memory requirements are considerably lower than those of Windows Vista, Windows 7 and Mac OS. It has an attractive and configurable user interface that operates faster on older hardware than the competition. It supports most 32-bit and 64-bit software, can operate with enormous amounts of memory and maintains compatibility with applications designed for Windows NT, 2000, 98, 95, ME and even earlier.

Windows XP's Service Packs can be downloaded from this software archive, through the Microsoft web site or using the built-in Windows Update service. Verify installer integrity before launching the program to be sure that you have the latest possible version. Remember to look out for subsequent updates while you are waiting for the next service pack version.
