Consider the following scenario. You play some media content in Windows Media Player 10 or in an application that uses the Windows Media Player 10 ActiveX control. Next, you click the Stop button, and then you click the Play button. If you repeatedly perform this "play-stop-play" operation, a memory leak occurs. You can verify this memory leak by using one of the following methods:
In Windows Task Manager, notice that the memory usage increases during the "play-stop-play" operation.
In Performance Monitor (Perfmon.exe), add the Private Bytes counter and the Virtual Bytes counter. Then, notice that the values of these counters increase during the "play-stop-play" operation.
These counters are under the Process performance object in Performance Monitor.
This problem does not occur in Windows Media Player 11.
This problem occurs because some unnecessary memory is not released in the Wmp.dll assembly.
