On November 29th, 2016 release 1607 of Windows 10 became “Current Branch For Business” (CBB) and 1607 will start being deployed to all 1507 Machines as of January 2017. Microsoft has a ‘2 version’ rule that states Microsoft will support and make patches for only two releases of Windows 10 + 60 days. All this means the 60 day countdown to death for Windows 10 starts in January:
- Windows 10 Release RTM 1507 – released July 2015 – dead March 2017
- Windows 10 1511 – released November 2015 – dead TBD but likely fall 2017
- Windows 10 1607 – released July 2016 – dead TDB but likely spring 2018
To clarify a few points:
- In addition to all the common tools you likely already know about Microsoft has new Upgrade Analytics Tool for Business you can run for free directly from Microsoft Azure.
- Microsoft expects to release 2 or 3 new versions every year and no longer releases service packs
- Unless a serious problem is found a release version called Current Branch (CB) will declared Current Branch For Windows (CBB) by Microsoft 4 months after CB release
- Microsoft will update media and published it in January (to Windows Update and WSUS; ConfigMgr gets it from WSUS). At that point, ConfigMgr should indicate that Windows 10 1607 is CBB
- If DEFER UPGRADES is enabled that makes you CBB which means you will see 1607 deployed in January 2017
- If DEFER UPGRADES is enabled AND you have a GPO set AFTER A FEATURE UPDATE IS RELEASED, DEFER RECEIVING IN FOR THIS MANY DAYS, that number of days starts counting in January 2017
