Windows 7 network game delay is too high solution

I often hear people say that when using Win7 to play online games, the network delay is relatively high, that is, the ping is higher than the usual xp, and the reason has been found, it is very distressing. Today we finally found a reason, it turned out that a service of Win7 is at work, this service is called: Multimedia Class Scheduler.

The official interpretation of this service is:
The Multimedia Class Scheduler service (MMCSS) enables multimedia applications to ensure that their time-sensitive processing receives prioritized access to CPU resources. 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 determines the relative priority of threads performing these tasks. 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

This service makes my PING so high, the problem 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), and finally Save and exit.

After the computer is restarted, the settings will take effect, then disable and disable the Multimedia Class Scheduler in the service, and then enter the game to see if there is any improvement.
