After reporting that Microsoft will be charging up to twice as much for the full version of Windows 7E in Europe compared to Windows 7 in the United States, Microsoft was not charging more because of the anti-trust regulators in Europe.
Consumers can purchase an upgrade for as little as $199 in the U.S. whilst Europeans will pay €309 or $433.99 (US) for the full version.
Microsoft states the reason for the missing upgrade of Windows 7 is that Vista came with Internet Explorer 8 pre-installed, while Windows 7E will not. Due to complications, and a short notice to fix the IE8 problem, the upgrade versions are delayed. The European Union antitrust regulators have pressured Microsoft to ship a customized edition of Windows 7 in Europe without IE8. This will cause problems upgrading previous systems who have IE7 installed already, as for now, Microsoft does not have an upgrade edition of Windows 7E.
Microsoft released a limited time offer price on their full version of Windows 7E up until December 31, 2009, where consumers can purchase a copy of Windows 7E for the same price as U.S. consumers upgrade edition.
Now Europe will pay less for their version of Windows 7E full edition than people in the United States Windows 7 full edition.
Update: A change was made to the article about Microsoft responding to adjust prices, while there was no responses to the matter.
