DirectX 11 is a graphics technology application created by Microsoft for use with the Windows operating systems. DirectX 11 is designed to improve gaming technology. For example, DirectX 11 improves graphic details and creates faster frame rates for games. DirectX 11 is installed automatically by Microsoft and cannot be uninstalled through the "Windows Uninstall or Change a Program" feature. Fortunately, you can uninstall DirectX 11 using the Windows Registry Editor. Note that the steps described apply to Windows Vista and 7.
Click "Start," right-click "Computer" and select "Properties." The System Properties window opens.
Click "System Protection" in the left pane of the System Properties window.
Click "C:Drive" under Protection Settings, and then click "Configure."
Click "Turn Off System Protection," then click "OK," and then click "OK" again. This will prevent Windows from reinstalling DirectX automatically once you reboot after you uninstall it.
Click "Start," type "regedit" into the "Search" box, and press "Enter." The Registry Editor opens.
Click the "Arrow" next to "HKEY_LOCAL_MACHINE" in the left pane of the Registry Editor. A list of folders appears.
Click the "Arrow" next to the "Software" folder in the left pane of the Registry Editor. A new list of folders appears.
Click the "Arrow" next to the "Microsoft" folder in the left pane of the Registry Editor. A new list of folders appears.
