Make it uninstallable
I agree with Rob Elliott with the primary issues being that IE is too integrated into the OS and can't be uninstalled.
An OS needs a browser nowadays, but whereas it can be uninstalled without many problems in other OSs and the user can choose which browser to use or not to have a browser at all, in Windows you cannot uninstall IE, so even if you choose to install FF/Safari/Chrome/Mozilla/Opera or whatever you want to use, you always have IE lurking in the background, wasting space and demanding regular security updates.
MS did abuse it's market position and continues to do so even though many complained.
So why not either provide a slimmed down no-feature-browser if there has to be one to display the windows help and whatnot and let the user decide which browser they want to use by either providing an overview page with links to the biggest alternatives including the full IE7/8 or, in the least provide an option to get rid of the thing if people don't want it...
