Good news, an actually good Windows update is here. But it likely won't be useful for a while. Still, the foundation has been laid for your apps to update themselves thanks to the introduction of the Unified Update Orchestration Platform (UOP).
The UOP will "download and install updates based on user activity and system state". Though rather than Windows Update, which provides patches for the OS and some applications and services, or Microsoft Store, UOP allows apps to stick to their own backend updating service. So, think of it like the OS helping apps to download updates when the system isn't in use.
