permanent removal of sound scheme

I want to permanently set my Vista sound scheme to "no sounds", however some program keeps modifing my "no sounds" setting to "no sounds (modified)". I suspect there must be some registry setting that I can make to dis-allow unauthorized modifications to my "no sounds" scheme. Any clues?
Thanks in advance,
Ed

This is an unusual request....I'm curious to know why you would not want any of those system sounds....I gues it's none of my business.

I often make recordings of audio programs (radio and feeds) while on the computer. With my system the assorted beeps and boops get recordered also. Moreover it is just the principle of me setting my sound scheme to my choice of "no sounds" and then having some program usurp my choice and override my option of "no sounds" to "no sounds(modified)". I want to have the control of making my choice permanent.
