multimedia class scheduler服务的官方解释是： the multimedia class scheduler service (mmcss) enables multimedia applications to ensure that their time-sensitive processing receives prioritized access to cpu resources. this service enables multimedia applications to utilize as much of the cpu as possible without denying cpu resources to lower-priority applications. mmcss uses information stored in the registry to identify supported tasks and determine the relative priority of threads performing these tasks. each thread that is performing work related to a particular task calls the avsetmmmaxthreadcharacteristics or avsetmmthreadcharacteristics function to inform mmcss that it is working on that task. for an example of a program that uses mmcss, see exclusive-mode streams 我个人认为的简单解释就是：多媒体类计划程序服务（mmcss）让多媒体应用得到尽可能多的cpu时间 可以禁用的 顺便再说一句：据说禁用multimedia class scheduler服务还可以解决win7下网络游戏ping的时候ms值高的问题：方法如下： 开始--运行-regedit，展开[hkey_local_machine/system /currentcontrolset/services/audiosrv]双击打开右侧的dependonservice项目，把mmcss删除（千万别删到其他的），重启电脑后到服务里关闭并禁用multimedia class scheduler就行了
