Customers using Windows Update for Business will lose some ability to delay the deployment of each new Windows feature release once version 1903 goes live.
When Microsoft first started delivering Windows 10 “as a Service” with a regular flow of feature updates, the company planned to have two release tracks: a “Current Branch” (CB) that was consumer-oriented and “Current Branch for Business” (CBB) aimed at enterprises. The CBB track would trail the CB one by a few months, with consumers acting as guinea pigs to iron out bugs before the quality of each release was deemed good enough for corporate customers.
