How to change file type associations in Windows 7

October 26, 2009

Windows 7 logo Associating different programs with certain file types makes those files easy to open or listen to.  For instance, associating Microsoft Word with .doc files allows you to quickly open word files when you download them.  Other files can be associated with a variety of different programs.  Gif files, a type of picture file, can be opened by many different programs like Internet Explorer, Paint, Windows Media Player, Picasa and other photo/picture viewers.  What happens if your pictures or music don’t open in your preferred program? When that happens you need to change the file type association.

The first way of doing this in Windows 7 is to click on Start.

Start button

In the right hand menu click on default programs.

Once that opens click on Associate a file type or or protocol with a program.
