在win7下网络游戏ping高的问题解决方法

　win7的使用可能大家都不太熟悉，在windows 7下玩游戏经常会出现很多的问题，最多的就是驱动和显卡配置的问题。有些服务可能导致win7下的服务出现问题，比如Multimedia Class Scheduler服务，它能够让win7下的网络游戏ping比平时高。到底是怎么回事呢？笔者来给大家做个讲解：  　　Multimedia Class Scheduler服务是什么？  　　官方给出的解释是: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  　　就是这个服务让我的PING如此高，问题是找到了，那么我们如何解决呢？很简单，禁用它就行了。  　　禁用方法：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），保存。  　　重启计算机后设置才会生效，然后到服务里关闭并禁用Multimedia Class Scheduler，再进游戏看看有没有提高呢？
