Sinful Devices

Just curious ... now everyone knows you can barely uninstall directx 9. I wish i knew how. I just bought Starfleet Command 3 and i have directx 9 installed it says i need 8.1 or higher. SO the questions is .. if i cant uninstall this .. does anyone know any software where i can emulate and fool windows or the games into thinkining i have 8.1 running ... thank you.
