There are going to be three
Windows 10 servicing branches when the product launches: Current Branch (CB), Current Branch for
Business (CBB) and Long Term Servicing Branch (LTSB). Different versions of Windows 10 will give users access to different servicing branches.
Those running Windows 10 Home will have just one choice -- the Current Branch.
Those running Windows 10 Pro are going to have two options: Current Branch or Current Branch for Business. The CB means, as with Home, that users will have to take all feature fixes and security updates as they're made available by
Microsoft via Windows Update. But the CBB option will give Pro users more flexibility about when they apply the new features, fixes and security updates from Microsoft.
First off, those who have access to the CBB will have a choice of how they get these updates. They'll be able to use Windows Update, Windows Update for Business or Windows Server Update Services (WSUS) to push these updates to users.
I've heard from one of my contacts that Microsoft is planning to allow those with access to the CBB to defer new feature updates for Windows 10 only for a set period of time. But they cannot defer them indefinitely.
Those who are on Windows 10 Enterprise -- the most expensive and most fully-featured version of Windows 10 (and one that's available only to Volume Licensees) -- get the most choice.
The only group of customers that will have the option to refuse completely new features that Microsoft delivers as part of its Windows 10 as a service strategy are Windows 10 Enterprise users.
The only customers who can continue to use WSUS to control how/when they apply new patches, features and fixes to Windows 10 are Pro, Enterprise and Education users. If you take Microsoft's "free for the first year" upgrade deal to Windows 10, you won't have the option to use WSUS or Windows for Business -- only Windows Update.
