The Codec Tweak Tool has the ability to scan for broken filters and remove them. If the tool detects something that is broken, it will prompt you with the details and you will be given the option to remove the broken item.

With this tool you can do things like:

* Scan the registry to detect and remove broken references to codecs and filters.
* Generate a detailed log of all installed codecs and filters.
* Enable/disable over 150 codecs and filters (if they are installed)
* Reset FFDShow to the recommended settings
* Fix non working system sound and more...
