Paul Thurrott posted a preview on the Windows 7 E Editions

It may be a while before we know whether Microsoft's decision to offer special "E" versions of Windows 7 in Europe--that is, versions of Windows 7 that do not include Internet Explorer--is crazy like a fox or just plain crazy. But there's little doubt that the software giant's answer to the increasingly irrational antitrust regulators in the EU is inventive. Rather than kowtow to the EU's demands that it bundle competing web browsers in Windows 7 via a so-called ballot screen, Microsoft simply removed the source of the problem. In the Windows 7 E Editions, which will be provided to all of its customers in the EU, Internet Explorer simply isn't included. And you can't add it back via Programs and Features as you can in versions of Windows 7 that will be sold elsewhere around the world.
