registry iconA few weeks ago, I told you how to repair the default image file types in Windows XP. At the time, I wasn’t aware of any utilities that could help you restore file types in Vista or Windows 7. I should have guessed that Ramesh Srinivasan would make good on his word. I had seen an old post which said he’d be working on something to help out.

Why would you need to restore a default file type?

You probably already know that a file type is controlled by the last letters after the dot in a file name. When you install new applications, sometimes the new app takes over the opening of some file types automatically. If you installed a new music player, you might discover that all .MP3 files now open up in the new player. That’s fine if you like the new player, but what if you don’t? You can re-assign the MP3 file type to another player by using the “Open With” menu when you right click on an MP3.

If you want Windows to use the default player that Microsoft had originally chosen for MP3 files, you might have trouble figuring out how to do that. I have found that it’s also sometimes tricky to get the defaults back on image file types. Fortunately, there are a few scripts and utilities that can help.

Using .REG Scripts

Ramesh has a page on his site that helps you restore a few Windows 7 file types to their defaults. He also has a page that lets you restore Vista file types to their defaults. Read the instructions on those pages to use REG (registry) scripts to make the changes.

Here’s a list of the file types that can be changed there:

AUDIOCD, AVI, BAT, BMP, CHM, CMD, COM, DVR-MS, EXE, GIF, HTM, HTML, ICO, INF, IMG, JPE, JPEG, JPG, JS, LNK, MP3, MPE, MPG, MSC, MPEG, REG, SCR, TIF, TIFF, TXT, VBS, WMA, WMV, WSF, XML, XPS, ZIP, FOLDER, DIRECTORY, DRIVE
