Internet Explorer 8 becomes a gentleman today
Previously, the installer's Express mode would automatically set IE as your default browser without so much as an "excuse me." That's no longer the case. As stated in the official blog post, "IE will never install, or become the default browser without your explicit consent."
In a nutshell, if you're the click-first-and-read-warnings-later type, you no longer have to worry about your browser of choice getting hijacked during a Windows Update-related mishap. The change is all part of Microsoft's commitment to user choice and control. Stop snickering.
Clearly Microsoft has learned not to make the same mistake as Corbin Dallas.
