Part 1: How to Play AVI Files with Windows Media Player

There are two fairly common reasons why Windows Media Player (WMP) stops to play AVI files. First is that AVI files are no longer associated with WMP. To fix this, open WMP and press Alt to show the menu. From the Tools menu choose Options… In the window that opens, click the File Types tab (note that this doesn’t exist in WMP 12, only in previous versions). Check that Windows video file (.avi) is ticked and, if it isn’t, tick it and click OK.

If Windows Media Player still can’t play AVI files, you could then try to update your Windows Media Player. Press Alt key to show the menu if you can’t see it and then choose "Help > Check for updates…" and follow the on-screen instructions.
