After confirming the rumored July 29 release date for Windows 10, Microsoft has now confirmed the pricing for its new operating system.

As previously announced, upgrades from Windows 7 or Windows 8/8.1 are free for the first year of availability. Windows 7 Starter, Home Basic, Home Premium, and Windows 8/8.1 users will receive Windows 10 Home. Windows 7 Professional, Ultimate, and Windows 8.1 Pro users will receive Windows 10 Pro. Enterprise users get nothing, because upgrading is usually taken care of as part of their license agreement anyway.

But if you're building a new PC or using an operating system older than Windows 7, then you'll need a full non-upgrade version of the operating system, which won't be free. Microsoft has told Neowin that Windows 10 Home will have an estimated retail price of $119. The Pro version will be around $199, and upgrading from Home to Pro will cost $99.
