Windows Vista：修订间差异

2009 年 5 月，Microsoft 发布了 Windows Vista 的第二个也是最后一个 Service Pack，其中包括各种新功能，如无线和蓝牙支持；最值得注意的是，蓝牙[[控制面板]]小程序；它还包括内置的 Windows Search 4.0，更好地支持 eSATA 驱动器，支持在蓝光光盘上刻录和对 x64 VIA Nano 处理器的支持，还改进了 RSS 源[[Windows 边栏|边栏]]小工具的性能，并改进了流式高清内容。Service Pack 2 略有不同，因为它至少需要安装 Service Pack 1 才能更新实时操作系统。另一个更新称为 Windows Vista 平台更新，于 2009 年 10 月发布，包括 Windows Automation API 和 Windows Ribbon API。Service Pack 2 是 Windows Vista 在被 [[Windows 7]] 取代之前的最后一次更新。
