Existing genuine VISTA users will be able to upgrade to WINDOWS7

for free. To attract users who are not ready to purchase new computers, Microsoft said it will also offer limited bookings at prices as low as $50. Users who have purchased Windows Vista Home Premium, Enterprise and Ultimate will be able to contact their computer manufacturer starting Friday and upgrade to Windows 7 for free after October 22.
Microsoft said it expects $300 million in revenue to be deferred to subsequent quarters. In addition, Microsoft also announced the price of each version of Windows 7. The Windows 7 Home Premium is $120, which is $10 less than the Windows Vista Home Premium, and the Windows 7 Professional and Ultimate versions are $200 and $220, respectively, which is the same price as the Windows Vista version.
Whether it's an XP system or a Vista system, it's the same when upgrading to Windows 7. To boost initial sales and increase impact, Microsoft is preparing to cut the price of Windows 7 by half, with the Home Premium at $50 and the Professional Edition at $100. From Friday, consumers in the US, Canada and Japan can book, and consumers from the UK, France and Germany can book from July 15. The reservation will last for about 2 weeks, but the number of reservations is limited. Consumers can go to Microsoft's download site or retailers such as Best Buy to buy.
