[German]Windows 10 RTM (Build 10240, Version 1607) has been released on July 29, 2015. Now Microsoft mentioned, that support for this version will end on March 26, 2017.
Microsoft made several announcements in a blog post Windows 10 v1607 media now available published on January 19, 2017. Windows 10, version 1607 was declared the Current Branch for Business (CBB) on November 29, 2016.

Windows 10, Version 1507 reaches End of Service
After 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. 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 Microsoft didn’t mentions: Windows 10 Enterprise RTM LTSB (Build 10240) is still maintained (the end of life time is 10 years after release). So cumulative updates should be available after March 2017. We have to test, whether it’s possible to download cumulative Updates for Windows 10 Enterprise RTM LTSB (Build 10240) from Windows Update Catalog and install it manually under Windows 10 Home/Pro (Build 10240).
