How to unassociate File Types in Windows 7!

It drove me nearly crazy yesterday, when I falsely associated a few files with the wrong application and could unsassociate them.

No mater how much I turned my registry upside down, how much I deleted, something was missing. I just couldn't find it. "F'k it!" I thought, and turned to google.

Lo and behold, I stumbled upon Unassoc. Simple, small, no installation! Oorah!


Simply search for the desired file type and click "remove file association (user)", after that Windows 7 will use the global file association. If you still have the wrong application as your standard application then do "delete file type".

  1. Nope. Tried the unassociation program. The first time the “remove” button was disabled. I then associated another program with the file using Windows Explorer. The next time I tried the unassociation program the button was enabled, but the default program still did not change.
