Last week a particular patent submitted by Apple outlined its plan to bring the mobile virtual assistant Siri to the desktop. It looks like Microsoft might be planning the same thing by brining the Windows 8.1 voice assistant Cortana into Windows 9 proper. Cortana has actually been running within Threshold—Microsoft’s codenamed OS build widely belived to be Windows 9—for some time, according to Neowin, but now the integration looks like it’s moving forward. Neowin describes Cortana’s “graduation” from a testing stage to a “let us push this forward and see if we can ship it” stage.
