Last year Microsoft released Service Pack 2 for Windows XP. This was more than just a collection of security related updates but we sam some major updates as well such as: Security center, a guide for creating wireless networks and an updated firewall to name a few. However Microsoft will continue to update and keep WIndows XP up to date even after Windows Vista has been launched. Shortly after the launch of Vista Service Pack 3 for Windows XP will be launched with some features that has been borrowed from its younger sibbling. We’ve heard rumours of an updated WinFX, but also DRM.
