C-Major Audio

Overview

C-Major Audio is a software program developed by SigmaTel. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The setup package generally installs about 17 files and is usually about 712.93 KB (730,037 bytes). Relative to the overall usage of users who have this installed on their PCs, most are running Windows XP and Windows 7 (SP1). While about 70% of users of C-Major Audio come from the United States, it is also popular in United Kingdom and Germany.
