How do I change file extension associations?

I recently installed winrar. Now all of my .iso files are associated with winrar. Now in my archives, I know I had some zipped .isos, and I'm downloading a zipped .iso now. So there is confusion. Do I burn or unzip that Linux .iso I downloaded 18 months ago?

How do I get my .iso files to automatically be associated with Nero again?

Shift + right-click > Open with..., check the box at the bottom, then select Nero, and click OK.

or, in Explorer/My Computer, Tools > Folder Options > File Types, and change it there.

Thanks for that. It worked, but the tiles still have the stack of books (winrar type) as an icon. But it does open in nero.

Yeah...most of my video files have the winamp icon, yet open in WMP.

I think there's a registry key for each extension that points to the icon within the respective Program Files directory. I should look when I get home, or maybe even run a RegClean to see if it just needs to be cleaned up.
