Microsoft is ending support for the original version of Windows 10 that was released in July 2015. In a post for its business customers, the Redmond software maker confirmed that the company will end support for Windows 10 version 1507 on March 26, 2017.

End of servicing for Windows 10 version 1507

Following this, the original Windows 10 version will no longer receive any feature or security updates from Microsoft. While most of the everyday users are now on Windows 10 Anniversary Update (or at least the version 1511 released in November, 2015), some enterprise computers are still running on the first version released in 2015. Since the version will no longer receive any security updates, it could pose potential security concerns, making it almost a mandatory update.

Earlier last year, Microsoft had shared with its customers on how it plans to support the new Windows as a Service paradigm. By ending support for older versions of Windows 10, the company aims to get a more macOS-like update system where most of the systems are running the latest versions of the operating system. The company had promised that it will support only the two most recent "feature updates" of the OS. Since Windows 10 Creators Update is due to be released in April, the company will only support Windows 10 Anniversary Update (version 1607) and Windows 10 version 1511.

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.

Windows 10 Anniversary Update, on the other hand, is coming toVolume Licensing Service Center (VLSC) on January 26. This also means that once Creators Update hits VLSC later this year, version 1511 will also get 60 days of grace period before Microsoft ends support.
