Microsoft is likely to roll out the Windows 10 Fall Update on November 10, delivering all updates that have been released for the operating system since July 29 as a cumulative patch. The update is also set to bring new features to Cortana, along with official support for Indian customers.
That's according to a Microsoft support engineer in response to a customer query:
Cortana will be available in India after November update releasing on November 10th, 2015.
Other features that will be available in the update include improvements to the Edge browser and an improved Media Creation Tool. Additional features will be making their way to the OS in the summer of 2016 with the Redstone update, which will include the ability to make phone calls through a Windows 10 desktop that's paired with a Windows 10 Mobile phone.
