Windows 7 Codec Pack is just next to Win7codecs one of the most popular filter packages and audio/video codecs dedicated to users of Windows 7 or later. It allows you to play movies in most of the most popular formats and what is extremely important in the case of this type of software does not litter the disk, system registry, etc., installing only the most important components. Windows 7 Codec Pack does not reduce system performance and, which is equally important, does not cause conflicts if other codecs or even entire packages have already been installed on your computer.
