The opt-in mode will be aimed for home users, who will allow to get access to new features, fixes, and security patches as they are ready. The lock-down mode, on the other hand, will be for businesses and it will only limit to regular updates to prevent compatibility issues with businesses configurations. Though, it’s unclear yet how businesses will push new features when they are ready to deploy. Nonetheless, it’s good to hear that Microsoft will offer an opt-in and lock-down mode to keep moving forward and making everyone happy in the process.
