A new post on the official Windows 7 team blog has announced that the Windows 7 Family Pack will also be available to many European countries (UK, Ireland, Germany, France, Switzerland, Austria, the Netherlands and Sweden - alongside the US and Canada):
You can read more information on the MS Team Blog and at PC World.The Family Pack allows users to install Windows 7 Home Premium for a reduced price on up to three PCs in a household that already has a version of Windows installed. Like the U.S. offer, the European offer is for a limited time. The company did not assign the offer a deadline but said it is only while supplies last.
Microsoft is able to offer Windows 7 Family Pack in Europe because it reversed a decision to pull IE 8 out of the OS there. Instead, it will offer Windows 7 with IE pre-installed and a ballot-screen option so users can install a competitive browser, LeBlanc said. This allows Microsoft to have a version of Windows 7 that users in Europe can upgrade to in October, he said.
