Right on schedule, Microsoft has begun taking pre-orders for Windows 7. In the US anyway. Customers in the rest of the world will have to wait a little longer. But if you're in the US you can pre-order Windows 7 upgrade packages for about half off, bringing the price of Windows 7 Home Premium upgrade to $49.99 and Windows 7 Professional Upgrade to $99.99.

Windows 7 Ultimate Upgrade will still set you back full price, or about $219.99 And at least at Amazon, there are no discounts for full retail versions of the operating systems yet. That means you'll end up paying $199.99 for Home Premium, $299.99 for Professional, and $319.99 for Ultimate.

All versions have a release date of October 22nd. Amazon is limiting pre-orders on Windows 7 Home Premium Upgrade and Windows 7 Professional Upgrade to 3 per customer, and the pre-order pricing expires on July 11th or once Microsoft sells a set number of pre-orders. Not that anybody knows exactly what that magic number is.
