Help me! I want to completely remove DATA EXECUTION PREVENTION from my computer?!!!?

I'm so irritated by the DEP Warning when I'm using my Canon ip1700 PRINTER. If I turn on the DEP for all programs with Run DLL as AN App (rundll32exe) exempted, other programs such as Hangaroo get DEP Warnings and do not open. Now, I WANT TO REMOVE DEP COMPLETELY...no DEP FOR ANY SINGLE FILE!!! Help me! thanks!
