I frequently run an application (Tunebite) that processes as many as 20 audio streams simultaneously, playing the tracks in real time, removing DRM, and encoding them as MP3 files.

This is an extremely CPU and memory intensive process, so much so that if some background task starts up (such as an AVG update or a Windows update of any sort) it corrupts some of the audio tracks.

Is there a simple way to temporarily turn off multi-tasking in Windows Vista so that when Tunebite is running, it remains the only application in process?
