Windows 7 aims to improve on its predecessor Vista by simplifying everyday tasks after listening to feedback from billions of customers around the world.Online retailer Amazon.co.uk said the operating system was now its 'biggest grossing pre-order product of all time', having overtaken the likes of Harry Potter and the Deathly Hallows and Nintendo Wii.
Sales may have been bumped by the well-received Beta version, which had favourable reviews from various technology websites.
The latest features include a redesigned taskbar with less clutter, a tool showing the status of connected devices including cameras and mobile phones, and quicker, slicker previews of an application's open windows.
James Gorbold, deputy editor of Custom PC, said: 'It's a massive step forward from Vista.'
He said Vista was annoying frustrating, and came at too high a price while Windows 7 'sorts out these problems and adds lots of useful features'.
'It's a lot faster and much more responsive,' he said.
The versions PC users are most likely to see for sale are the Home Premium and Professional editions. A Home Premium software upgrade will cost £79.99 until 1 January 2010, at which point it will go up to £99.99. The full version costs £149.99. (Daily Mail)
