There is a somewhat controversial change to how Windows update works in WIndows 10.
For Windows 10 Home users, there is no way to turn off automatic updates and they will be mandatory.
Windows 10 Pro users will have a little flexibility; they’ll be able to switch from the mainstream release to the “Current Branch for Business (CBB).”
This will give some control over when updates are deployed.
While the CBB will essentially track the consumer release, it will allow feature updates to be held back for some amount of time so you can prepare for the update.
Windows 10 Enterprise is the only OS for which users will be able to actually turn off Windows updates. By opting for the Long Term Servicing (LTS) branch, Enterprise users will be able to defer feature updates for years, electing to receive only security fixes during that time.
