Firefox is set to be my default browser. How can I change it to Internet Explorer.

- start Internet Explorer (if not already running)
- choose Internet Options from the Tools menu
- click on the Programs tab
- check "Internet Explorer should check to see whether it is the default browser" (at bottom)
- click OK
- close Internet Explorer

- start Internet Explorer (again)
- it should say it's not your default browser and ask if you want to make it so
- click Yes
