Microsoft announced Threshold 1 support extended
Microsoft has extended the date for TH1 support quietly as they have recently updated a Technet blog post. The following is a snippet of what Microsoft has said now:
“With the availability of Windows 10, version 1607 to the VLSC on January 26th, the grace period for Windows 10, version 1507 will begin. That means, after May 2017, Windows 10, version 1507 will no longer be serviced as only the two most Current Branch for Business (CBB) versions are actively serviced,” Microsoft’s blog post now reads (note that the March target was modified to “May.”)
They quietly changed March to May, which may be linked to the Postponement of February updates. The number of people running TH1 is still unknown, but Microsoft wants to give users at least one more chance.
