Windows Movie Maker is a free program included with Microsoft Windows that allows you to edit video and audio files, including those played in your Windows Media Player. From creating your own home movies for a family reunion to making ring tones for your phone, there are dozens of ways in which you can edit your files and impress friends and family. You can then burn the files to a CD or DVD. Movie Maker saves the video and audio files in a WMV or WMA format, respectively, both of which are supported by Windows Media Player.
Open Windows Movie Maker by right-clicking on the "Start Menu" button, selecting "All Programs" and then scrolling to "Windows Movie Maker."
Right-click on "Windows Movie Maker" and select "Pin to Start Menu." This will pin the program to your Start Menu and save you time in the event that you accidentally close the program while editing. Then click to open it.
Import the Windows Media Player file that you want to edit into Windows Movie Maker. Select "Import Media," browse to the file and click "Import." The click will appear in the top pane.
Drag the file to the "Timeline" window at the bottom of the screen. Here, you can view your audio or video track in its entirety, which will allow you to edit at the exact second. Be sure to line up the track so that it starts at "00:00," unless you want the edited version to start later. In that case, drag the track to the moment in the timeline when you want the track to start.
Click the "Play" button to begin playing the file.
Click the "Split" button at the moment you want the file to split and delete the segment you want removed. Continue to split the track as needed until you are satisfied with the final product.
Click "This Computer" under "Publish to." In the "Publish Movie" window, name the file, select a location to save the file to and click "Next."
Choose the quality setting you wish to use."Best quality for playback on my computer" is selected by default. Once you have made the proper quality selection, click "Publish," and your audio clip will be saved to the location you specified.
