Windows 10 Anniversary Update rollout will take 3 months...or: Microsoft uses consumers to test Win 10 patches, before deploying to Enterprise users.http://arstechnica.com/information-technology/2016/09/some-people-wont-get-augusts-windows-10-anniversary-update-until-november/Quote
The Windows 10 Anniversary Update's deployment process squarely positions mainstream consumers as an important part of the testing process. The Current Branch for Business (CBB), which is the mainstream corporate and enterprise offering, lags behind the consumer-oriented Current Branch. The CBB won't receive the Anniversary Update until some time after the consumer rollout is complete. The extra three months of testing should mean that the eventual corporate rollout is smoother than the consumer one. But many consumers will wonder why they have to serve as guinea pigs in the first place.
