Multimedia Class Scheduler Service (MMCSS) is a Windows service that boosts the CPU as well as I/O priority of a thread. It allows an application to get prioritized access to CPU for time-sensitive processing (such as multimedia applications) as well as prioritized disc access to ensure that the process is not starved off data to process. The MMCSS service monitors the CPU load and dynamically adjusts priority so that the application can use as much of CPU time as possible without denying CPU to lower priority application.Cite error: A <ref> tag is missing the closing </ref> (see the help page). or AvSetMmThreadCharacteristics()[1] APIs.
