Microsoft: Think twice about IE7 before upgrading to XP SP3

Uninstall IE7

Still haven't made up your mind about Internet Explorer 7? No problem, you can always uninstall it and revert to the Internet Explorer 6 web browser that came with your operating system. Unless you've upgraded to Windows XP SP3, that is. Because Microsoft is telling computer users that if they install IE7 before XP SP3, there's no going back.

Basically, when you install IE7, your IE6 files are saved in an uninstall directory that includes the original IE6 installation files and any security updates you've added over the years. But SP3 includes a different set of security updates. So if IE7 is already installed when you load SP3, the uninstall directory that was created when you were using SP2 is no longer valid.

If that's all a bit confusing, here's what you should take away: If you don't plan to use IE7, don't install it. Period. If you do plan to install it, but want to be able to uninstall it, then you should load Windows XP SP3 before upgrading from IE6 to IE7. If you upgraded Internet Explorer before installing XP SP3, the only way to uninstall it would be to uninstall the entire service pack, which is really far more trouble than its worth.
