Windows 10's first major update is called the Anniversary update is coming this Summer
This morning during the opening keynote for Microsoft's 2016 BUILD developer conference, Terry Myerson took the time to announce that there is not over 270 million Windows 10 users and also introduced an upcoming Windows 10 update which have previously been referred as 'redstone'. Called the Windows 10 Anniversary update, the new version of Windows 10 will be coming to users later this Summer, presumably by the time Windows 10's first anniversary hits.

As expected, this upcoming update will slowly trickling out to users in the Windows Insider program in the coming weeks. As for the actual features that will be bundled with this new Anniversary update, the list currently includes things like support for biometric security through select applications on Microsoft Edge, improved inking (Windows Ink) improvements with some visual tweaks and updated support for UWP apps. Just as before, this list will most likely grow as the weeks go by.
Microsoft says that the Windows 10 anniversary update will be rolling out to all Windows 10 PCs in the Summer and the update will be free to all Windows 10 users. While these features are only related to Windows 10 on the PC, expect to hear more details about the Windows 10 Anniversary update for other Windows devices like the XBOX and Mobile.
