SYMPTOMS
When you change settings in the DirectX tool in Control Panel, you may experience unexpected behavior. Note that the Directx.cpl file is the DirectX tool in Control Panel

CAUSE
This behavior can occur if you change any of the original settings in the DirectX tool.

RESOLUTION
To resolve this behavior, restore the original settings in the DirectX tool, and then restart your computer.

NOTE: It is impossible to determine what the original settings were unless you noted them. If you do not know the original settings, Microsoft suggests that you restore your system from a known good backup. If you do not have a backup copy of your system, you may need to install Windows into a new folder, and then install your programs again to re-create affected registry entries.

MORE INFORMATION
The DirectX tool is available only when you install the Microsoft DirectX Software Development Kit (SDK). It is designed only for developers to test DirectX programs under a variety of conditions. For example, it is used to turn off DirectX features to test games under "problem" conditions.

The DirectX tool is not designed to solve problems with DirectX. It is designed to review and alter DirectX configuration settings as DirectX- based programs are being developed. The original settings in the DirectX tool are based on installed hardware and drivers, and vary from computer to computer.
