Most music "rippers" used to create MP3 files have the ability to add information to the headers of the resulting files. These headers are called "ID3 tags" and they contain information about a song such as the artist, the title of the song and the album that the song is from. Occasionally, you might download music online that has incorrect ID3 tags or inadvertently add tags to a file containing personal information that you would like to remove. For this reason, Windows 7 gives you the ability to strip all ID3 headers from a file by accessing that file's properties.
Right-click the MP3 file from which you would like to remove the ID3 headers and select "Properties" from the context menu.
Click the "Details" tab at the top of the window and then click the blue "Remove Properties and Personal Information" link at the bottom.
Select the "Remove the following properties from this file" radio button at the top of the window.
Click the "Select All" button at the bottom of the window.
Click "OK." Windows removes all ID3 headers from the selected MP3 file.
These steps also work in Windows Vista.
