Microsoft informed users Windows 7 that they might come across issues when running VoIP (Voice over Internet Protocol) applications on their computers. According to Microsoft, “You run an application that performs audio playback and audio capture simultaneously. This is a typical scenario when your application is VoIP (Voice over Internet Protocol) software.” The application often hangs.
