Microsoft Is Retiring Windows 10 version 1507 On March 26

Microsoft has announced that it’s retiring the original release of Windows 10, i.e., version 1507. Now, Windows 10 v1507 won’t receive security and feature updates after March 26. It’s a part of Microsoft’s software-as-a-service model that says that it won’t support more than 2 CBB (Current Branch for Business) builds at a time. Now, the users are recommended to use Windows v1511 and v1607.

With the availability of Windows 10, version 1607 to the VLSC on January 26th, the 60-day grace period for Windows 10, version 1507 will begin. That means, after March 26th, 2017, Windows 10, version 1507 will no longer be serviced as only the two most Current Branch for Business (CBB) versions are actively serviced.”

Do they have a next scheduled upgrade soon?

The next big Windows 10 update is the Creators update, scheduled to arrive in Spring 2017.
