Restrict file upload in Internet explorer

Hi friends,

I want to disable file upload from internet explorer, firefox or any browser.
Is there any registry entries or methods we can do this.
Is it possible or not.

If disabling only upload is not possible than if we can disable download upload both than also it will be good.

guys. i have tried googling and all forums. msdn also. but not able to find it.

Help needed friends.

-Thanks for giving your time reading this.:o
