显然Services Pack更针对背景服务而不是前台功能。Bannan对装上SP1的系统进行Windows update看是否还需要其他的Vista更新，结果是不用。也就是说和我们预期的一样，Vista RTM以后的所有补丁都已经被整合到SP1中。
Vista SP1包：你可以卸载掉SP1的各个补丁包返回到原版Vista。
另外，别忘了我们之前报道过的Vista性能、兼容性补丁包。由于整合到Service Pack的补丁没有标上KB号，因此无法确定着两个补丁包是否被整合到SP1中。
目前有关SP1发布日期有许多谣言，但没有一个是真实肯定的。目前最靠谱的预测就是公众Beta将在今年晚些时候推出，而正式版就要等到2008年的某个时候了。
