Q&A for How to Uninstall Directx

Click "Start," and then click "Run." Type "dxdiag" (without the quotation marks) and then click "OK." On the "System" tab, note the version of DirectX that is displayed on the "DirectX Version" line.

If you do not have a system restore point and you want to un-install DirectX, then you will have to factory reset your device. It is wise before you do any major installations or before you do a major update to create a restore point. If you do, and something goes wrong, then you can simply restore to the point before the installation.

Most likely, you will need to keep an older directx version. Old games often need old DirectX Installed. For example, a DX9 only game probably won't work with DX10, DX11, and so on.

Every program has some - kind - of uninstall gear box that systematically removes what you or someone else installed into the computer. But if you leave it alone... it won't bother you.
