UK retailers have reported huge pre-order sales for Microsoft's new operating system, Windows 7, with the product becoming Amazon's biggest-grossing pre-order product. PC World-owner DSGi, meanwhile, has revealed that the OS has massively outstripped early sales of Windows Vista.
According to Amazon, Windows 7 has overtaken the Nintendo Wii and 'Harry Potter and the Deathly Hallows' as the most pre-ordered item on its website.
Amazon said in the last three months, only 'The Lost Symbol' - the highly anticipated novel by Dan Brown, author of The Da Vinci Code - has out-sold Windows 7 when it comes to pre-orders.
"The launch of Windows 7 has superseded everyone's expectations, storming ahead of 'Harry Potter and the Deathly Hallows' as the biggest-grossing pre-order product of all-time at Amazon.co.uk, and demand is still going strong," said Brian McBride, managing director of Amazon.
Amazon also revealed that when Windows 7 was first made available for pre-order in July this year, it sold more copies in the first eight hours of its release than Windows Vista managed in its entire pre-order period.
At DSGi, meanwhile, the retailer sold more copies of Windows 7 during the three weeks it was available on pre-order than it sold of Windows Vista for the first year the older OS was available.
