Using InstalledCodec
InstalledCodec doesn't require any installation process or additional DLL files. Just copy the executable file (InstalledCodec.exe) to any folder you like, and run it.

The main window of InstalledCodec displays the list of all Codec drivers and DirectShow filters. You can easily select one or more components, and then disable or enable them, export the information into text/xml/html file, or copy the information to the clipboard, and then paste it to Excel or OpenOffice spreadsheet.

Disable/Enable Codec drivers and DirectShow filters
If you install multiple Codec packages and other multimedia software on the same computer, you might find out that some multimedia files are not played properly as before. This problem is occurred if Windows Media Player (or any other player) uses the codec or filter of the newly installed multimedia software.

If you install a new Codec package and something goes wrong, you can try to fix the problem disabling the newly installed components. To easily find out the newly installed components, try to click the 'Installed/Modfied Time' column, the components list will be sorted by installation time, and then you'll find most of the newly installed Codec or DirectShow filters in the end of the list.
