Apparently Windows Blue, also known as Windows 8.1 will arrive this fall in the form of a free update for Windows 8. Microsoft CFO Tami Reller announced this news at JP Morgan’s Technology, Media and Telecom conference.
On 26 June a public release candidate version will be made available to users. This date marks the start of MS’s Build conference in San Francisko.
We hope to learn more about the changes introduced through the update in the meantime.Source: ARSTechnica
