The version will  work, it will not be updated.The strategy in line with Microsoft’s stop upgrade of Windows 10 and have only two CBB versions supported at the same time.

Microsoft decided the 60-day calculation for older CBB builds depends on the availability date of the newbuild in the VLSC.”With the launch of Windows 10, version 1607 to the VLSC on Jan. 26, the 60-day countdown for Windows 10 will start for version.”

As earlier mentioned, the original Windows 10 version 1507 will be working even after March 26, but it will not receive any security updates. This means that users currently using that version will be able to keep using it, but it’s highly suggested  to move to a newer version.Windows 10 users who are still running version 1507 are advised to update their software as soon as possible. Those who are running version 1607 don’t have to do anything.
