In yesterday’s tip, I pointed out how to use the Set Program Access and Defaults utility to change your default browser. When you use this tool, the browser you specify appears at the top of the Start menu and should open whenever you click a link.
In theory, that’s true. In practice, you may find that some types of shortcuts continue to open with your old browser. (The problem isn’t limited to Internet Explorer, either. If you experiment with different browsers you’ll find that most don’t do a good job of cleaning up after themselves.)
If you find that your old browser continues to open even after you’ve specified a new default browser, check your file associations to see if you can identify the problem. Open Control Panel, double-click Folder Options, and click the File Types tab. You’ll need to inspect the entries for six file types:
These three file types have no file name extension:
- Internet Shortcut
- URL:HyperText Transfer Protocol
- URL:HyperText Transfer Protocol with Privacy
These three file types have specific file name extensions:
- HTM – HTML Document
- HTML – HTML Document
- URL – URL File
On one of my PCs, I’ve specified Maxthon as the default browser, but as the screen here illustrates, the URL file type is still associated with Internet Explorer.

In this case, you can fix the problem fairly easily by clicking the Restore button. In other cases, you may need to click the Change button and choose your browser from a list of available options. If that option is not available, click the Advanced button (which appears where the Restore button is shown here) and edit the associations manually. This isn’t a job for the faint-hearted. You may need to enter a collection of obscure DDE commands to make the file type work properly. Your best bet is to look on another computer (one that hasn’t been customized) to see the correct settings and then copy those.
Great tip. Unfortunately, I still have issues with certain applications always opening links in IE regardless of the default browser settings. The primary culprits on my machine are MSN Messenger and OneNote. Do you know of any way to fix this or is this just an issue where these applications don’t properly obey default browser settings?
Thanks, Joe.
Some apps are just hard coded to use IE, unfortunately.

OneNote and Windows Messenger shortcuts open correctly in Firefox on my system. I suspect that MSN Messenger is the same.
Hi Ed,
Right now, I have windows XP and any hyperlink in an EXCEL worksheet is opening in IE even though NETSCAPE / FIREFOX is my default browser. Can u please help me with this ?
Thanks.
Hey Ed,
I am having this same issue with my computer in the office. I have checked the file associations mentioned above and they have no effect on links opened from Word to what should be firefox but is always IE. If IE had tabs this would not be so bad, but now i suffer with 15+ open windows when I do some research.
