Windows 7 to Harry Potter: Expelliarmus

Here’s an interesting Windows 7 stat as we near the operating system’s official release: It’s Amazon (AMZN) U.K.’s biggest pre-ordered product of all time. In fact, the online retailer has received more pre-orders for Windows 7 than it did for J.K. Rowling’s final “Harry Potter” book.

“The launch of Windows 7 has exceeded everyone’s expectations, storming ahead of Harry Potter and the Deathly Hallows as the biggest grossing pre-order product of all time at Amazon.co.uk,” Amazon’s Brian McBride told the Telegraph. “Demand is still going strong. Over the past three months, only Dan Brown’s The Lost Symbol has sold more copies than Windows 7, which is an incredible achievement for a software product.”

And an incredible achievement for Microsoft (MSFT), especially after that monument to disappointment, Windows Vista. Seems those early discounts and launch parties paid off. Well, maybe not the launch parties.
