Solve the high reason and method of online game PING under Win7

I often hear people say that when using Windows 7 to play online games, the network delay is relatively high, that is, ping is higher than usual when xp, has been unable to find the reason, very distressed. Today we finally found the reason. It turns out that a service of Win7 is at fault. This service is called: Multimedia Class Scheduler.

The official explanation for this service is:

The Multimedia Class Scheduler service (MMCSS The service allows multimedia applications to utilize as prior 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 determines 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.

Is this service makes my PING so high, ask Is found, then how do we solve it? Very simple, just disable it.

Disable method: Start--Run-regedit, expand [HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Audiosrv] Double-click to open the DependOnService project on the right, delete the MMCSS (do not delete it), save it. .
