Bugfixes and improvements for Windows Vista
Windows Vista Service Pack 2 is the final version of the second update package for Vista users. The service pack contains all the Vista updates released by Microsoft since Windows Vista Service Pack 1. These updates fix system problems and vulnerabilities. Service Pack 2 enhances wireless and Bluetooth connectivity and also features an updated version of Windows Search 4.0, which improves the comparably weak Windows search.
To run Service Pack 2, you must have Service Pack 1 installed already. Additionally, if you installed the release candidate, you'll need to uninstall it before installing this final version. With general system improvements and fixed vulnerabilities, Windows Vista Service Pack 2 is a must-have for all Windows Vista users.
