Microsoft announced on Thursday that the original release version of Windows 10 will reach the end of servicing on January 26, 2017.
Windows 10 version 1507 was released in July 2015 by Microsoft. It was the Windows 10 RTM version that Windows customers could purchase, or upgrade for free to.
Microsoft released two feature updates for Windows 10 since then. First the so-called November Update, released in November 2015, and then the Anniversary Update, released in August 2016.
Windows as a service is a new concept that Microsoft introduced with its Windows 10 operating system. The company introduced several new concepts, including servicing branches.
Windows 10 version 1507 EOL
There are three servicing branches, one reserved for the Enterprise, another for Professional versions (including Enterprise).
All Windows installations start in the Current Branch by default. Home users have no option but to stick with it, while Professional and Enterprise customers may switch to the Current Branch for Business instead.
The core difference is that feature upgrades become available at a later time for devices in that servicing branch, giving customers more time to test the changes before deployment.
Any Windows 10 feature update, including the first initial release of Windows 10 version 1507, will be supported for at least 18 months by Microsoft. It can be supported longer than that, as it depends on when feature updates are declared Current Branch for Business.
Microsoft will always support two Current Branch for Business releases at a time. The company made the Windows 10 Anniversary Update the second Current Branch for Business release (the first is the Windows 10 November Update).
With two CBB releases available, Windows 10 version 1507 is no longer one. There will always be a 60 day grace period for any release that falls out of CBB. This period begins on January 26th, 2017 for Windows 10, version 1507.
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.
What this means is that this particular version of Windows 10 will no longer be supported by Microsoft after that grace period. Windows 10, version 1507 reaches end of support on March 26th, 2017.
Microsoft won't release updates for that particular version of Windows 10 anymore after that date. Users may however upgrade to one of the two supported CBB releases, the November 2015 or the August 2016 versions of Windows 10 to continue receiving support.
Microsoft released media for Windows 10 version 1607, the most recent CBB release.
Today we are releasing updated media for Windows 10 v1607 (also known as the Windows 10 Anniversary Update) on Windows Update for Business, Windows Server Update Services (WSUS), and MSDN Subscriptions. We will also be releasing updated refreshed media for Windows 10, version 1607 to the Volume Licensing Service Center (VLSC) on January 26, 2017.
