Solutions to high PING for online games in WIN7 are often heard that network latency is relatively high when using Win7 to play online games, that is, ping is a little higher than xp at ordinary times, I was so worried that I couldn't find the cause. I finally found the reason today. It turns out that a service in Win7 is playing a strange role. This service is called Multimedia Class Scheduler.
This service makes my PING so high that the problem is found. How can we solve this problem? Www.2cto.com is simple. Just disable it.
Disable method:

Start -- run-regedit, expand [HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Audiosrv], double-click the DependOnService project on the right, and delete MMCSS (never delete it to others ), save and exit. After the computer is restarted, the settings will take effect. Then, go to the service and disable Multimedia Class Scheduler. Then, go to the game and check whether the settings have been improved.
