Current Branch for Business setting within Windows 10 Professional

The Current Branch for Business was released around four months after the Current Branch in the past, though this appears to be changing within the Fall Creator update time period.  The CBB was originally designed to give organizations time to test the new version.  To configure Windows 10 Professional to use this parameter, launch gpedit.msc with local administrative authority and navigate to Computer Configuration –> Administrative Templates –> Windows Components –> Windows Update –> Defer Windows Updates.  Modify the “Select with Feature Updates are received” entry and set it to Enabled.  Use the drop-down dialog box to select “Current Branch for Business” and enter a day value such as 90 days.


Another option at the same path is “Select when Quality Updates are received.”


This will delay the installation of monthly updates for the number of days that are specified.  When checking the Update section under Settings, a notification warning will appear stating some settings are hidden or managed.
