Cortana digital assistant to accompany Windows 9

Microsoft is set to include Cortana digital assistant in the next major version of Windows, which is expected to be named Windows 9.

Sources revealed that Cortana is a major area of investment for the release of the version, which is currently codenamed Threshold, and is expected to be in the market in spring 2015, the Verge reported.

Currently, Cortana exists as a separate app in Threshold, but Microsoft has been gradually improving it every two weeks by adding additional data points and features, and as the service is HTML driven, these improvements will make their way over to the Windows 9 version.
