As has been widely reported, MS has created a special edition of Windows 7 for the European Union called Windows 7 E. It will not have IE installed. This prevents upgrades from Vista. In the EU, you will only be able to get this E edition via retail chains – there will not be the normal edition. I suspect volume license purchasers will be able to get normal editions because they may be supporting users/customers outside of Europe.
This post tells you how to get a browser on your new Windows 7 E PC.
