There are four versions of the K-Lite Codec Pack: Basic, Standard, Full and Corporate.
&bull, Basic contains only the most essential things. It contains everything you need to be able to play the two most popular and widespread formats: DivX and XviD. With this you should be able to play DVDrips and TVrips.
&bull, Standard contains everything you need to play all the commonly used formats. This package should be enough for the average user.
&bull, Corporate Edition is a special version for use in a corporate environment. It is similar to the Full version, minus a few items, but almost just as powerful. It has a strong focus on open-source software.
The K-Lite Codec Pack is compatible with Windows 2000, XP, 2003, Vista, and Seven.
