Install this update to prevent an issue in which you may receive a â€œstop 0x7e in AEC.SYSâ€ error message on a computer that is running Windows XP Service Pack 2. The error may occur during startup, or after the system has started. AEC.SYS is the acoustic echo canceling driver. After you install this item, you may have to restart your computer.

Since when is an acoustic echo-canceling driver considered part of the operating system?
Why the heck does it have to be a driver?
One that produces a blue screen with a numbered error code?
One that can bring the whole OS to a grinding halt?
Why does it need to be loaded at startup?
