Codecs are a necessary component if you want to enjoy all kinds of multimedia content without image or sound problems. However they often end up being a nuisance due to compatibility and updating issues. This is precisely the kind of situation you can fix with K-Lite Codec Tweak Tool in a snap.
All you have to do is run this application (no installation required) and you'll be presented with an options menu where you can choose the actions you want to be performed by the program: fixing problems, enabling or disabling certain codecs or even generating a basic TXT report.
Although the program is not intended for novice users (you really need to know what you're tweaking and there's no help available), it's quite complete and works really well.
