How to check installed codecs on Windows 10

In this article, we will describe how to check installed Codecs on Windows 10. In the word codec, the first two letters stand for compression and the last three letters stand for decompression. Hence, a codec is a computer program that is used for the compression and decompression of a media file.

All the media players use codecs to play media files. You probably might have seen a message displayed by a particular media player, “Video codec is not supported” or “Audio codec is not available,” etc. This means that the media player does not have the required codec to play a video or audio file. The issue can be solved by downloading and installing the required codec.
