Windows 10 and Windows Server versions 1903 were released this week, but Microsoft also issued some notes for IT pros to consider. IT pros need to make some deployment tool settings changes before rolling out those operating systems. Also, Microsoft renewed its explanation about Windows 10 “targeted” channel releases going away and described some added perks available for Windows Update for Business users.

With Windows 10, version 1903, we are introducing new product categories to enable future support for the Unified Update Platform (UUP) for on-premises management solutions, which provides improved delivery technologies for Windows updates. A configuration change is, therefore, required for environments running the latest public release of Configuration Manager, as well as for environments using WSUS (without Configuration Manager) for updates.
