This is the box Windows 10 will come in

While most people will be downloading the Windows 10 update right from their computers, some people will be walking into retail stores to purchase the new operating system. New images have surfaced, showing off the design of the box, and they are quite simplistic. The update, which is set to release on July 29, will be available as a free download to Windows 7 and 8 users, but it won't be free for everyone.

Those who prefer to build their own computers, or want to run Windows 10 in a virtual machine, will need to purchase the OS. Microsoft is also apparently planning to sell the Windows 10 update on USB Flash drives, meaning even fewer are likely to ever see or own these boxes.
