What is a Video Codec?
Video codecs are regularly-changing “filters” that ensure videos you download to your PC can be played back through your favorite media player app. Audio codecs are often packaged alongside the video codecs, however these tend to be updated less often.
Codec packs can be downloaded and installed on your PC, and are often specific to a particular operating system. For instance you can download Windows XP video codecs, Windows Vista video codecs and Windows 7 video codecs.
Some codecs are built and distributed by Microsoft; others come from third parties. Windows 7 includes a selection of the most popular. Previous versions of Windows would only support basic WMV, AVI and MPEG video clips, while Windows 7 natively supports H.264, Xvid, and DivX formats.
If you’re new to Windows 7 and the video file you’re trying to watch isn’t working, your first course of action should be to download and install an update to the codecs that came included in the OS.
Finding Windows 7 Video Codecs
After installing or upgrading to Windows 7 you will find that you can play some video and audio clips but not all. Although the operating system includes video codecs, they might not be as up to date as those you can download from the web. Service packs, Windows Updates or later versions of Windows might have more up to date codecs – but you might prefer playing your video clip today rather than waiting a few weeks or months for an update!
As such, there are several websites online when you can download the most up to date Windows 7 video codecs.
These sites include:

Troubleshooting & Configuring Windows 7 Video Codecs
