K-Lite Mega Codec Pack 1.53

What is K-Lite Mega Codec Pack?

K-Lite Codec Pack is a collection of audio and video codecs for Microsoft Windows that enables the operating system and its software to play various audio and video formats generally not supported by the operating system itself. The Full edition includes 31 additional components and four additional tools beyond those included in the Standard edition, as well as adding video encoding capabilities to Microsoft Windows PCs. However, no encoding or conversion tool is included in the package.


During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The setup package generally installs about 64 files and is usually about 72.7 MB (76,231,068 bytes).
