Windows Vista Service Pack 2 RC (also called Vista SP2) fixes a range of bugs in Windows Vista discovered since the release of Vista Service Pack 1. The download provides enhanced security measures that will improve Vista’s defences against viruses, worms and hackers, along with increased stability and, fingers crossed, an improved experience for users.
Windows Vista Service Pack 2 is a large download and can be applied to any version of Windows Vista, provided Service Pack 1 has already been installed. You can download Vista SP2, burn it to disk and use it on multiple PCs.
Windows XP Service Pack 3 (XP SP3) fixes a range of bugs and adds new features to Windows XP. The file is a large download and can be applied to any version of Windows XP Home, Professional, TabletPC or Media Center (32 bit only). In addition, it doesn’t matter what XP patches you have previously applied to your system, SP3 will update any unpatched, partially patched or completely updated system to version SP3. It includes all features of Service Pack 1 and 2, plus all patches, updates and fixes released up to and including April 2008’s monthly security bulletin. Keep in mind that new patches made available after Service Pack 3 was released (mid April 2008) will still need to be applied.
