After announcing the launch of Windows 7 for next October 22 Microsoft has now unveiled the pricing structure that will have for different versions of its new operating system on their blog.

Basically, there are two different ranges, the full version to install on new computers and upgrade version where we already have Windows XP or Vista. Obviously, the upgrade will be cheaper, something that given the large amount of existing equipment, many can benefit.

Prices for this upgrade will be 119.99 dollars for Windows 7 Home Premium, 199.99 dollars for Windows 7 Professional and 219.99 dollars for Windows 7 Ultimate. For the full version, prices will be U.S. $ 199.99 Home Premium, from 299.99 dollars for the Professional and 319.99 dollars for the Ultimate. We still have to see how these prices get converted into Rupees INR.

Despite this, Microsoft will continue selling the upgrade version with the reduced price, but we must do to install it on a new computer, what it means to be backing up our data and applications, delete the contents of the disk and install on this.

Several manufacturers are starting to announce they will offer a free upgrade to Windows 7 on all computers purchased from now.
