How to Restore Default File Types in Vista and Windows 7

While looking around, I also found that Ramesh has a utility, named Unassoc, that lets you Unassociate User File Types in Vista and Windows 7. I learned that when you unassociate a User file type, it changes to the global file type. I many cases, that’s the original defaultfile type. Here’s how the Unassoc utility works.

unassoc-remove-user-filetype

When you launch Unassoc, you will only see one window with a list and five buttons. You can use the search window at the top to type in the type of file you are looking for. Just remember to put a dot in front of the letters. As you can see, I chose to remove the association I had created for JPEG files. After clicking the Remove file association (User)button, I saw this:

unassoc-removed-message

That’s a simple fix and I really appreciate Ramesh for making it available. I will caution you against using the Delete file typesbutton unless you are very sure that you understand what you are doing.

Download Unassoc

In case you don’t see the download link at WinHelpOnline, below, I’ve circled it’s location on the page. Don’t use that big green download button.

Techie Buzz Verdict:

Using .REG files to reset file types to default is sometimes a life saver for your PC. The Unassoc utility, for removing user file types, is a big plus, and I have no problems recommending it. The only reason I don’t score this utility higher, is that it’s not open source.

Techie Buzz Rating: 4/5 (Excellent)
