But fear not lazy and/or less-advanced Vista users! PreviewConfig makes it easy to add support for more file types. Simply open the application, choose the file type on the left and select how to preview it on the right. In the photo above, you can see the results of adding support for a multimedia file -- in this case an MP3 -- which is previewed through Windows Media Player.
Though it was easy to add support for MP3 files, adding more would require the user to go through the process again. This isn't a big deal if you're looking to add a few more, but adding support for 20, 30, or more file types could prove to be extra boring. Then again, it beats doing the registry hack over and over again.
