After Microsoft began making Windows 10 1903 available publicly this week, the company announced some changes in how its Configuration Manager and WSUS environments handle this update. The changes require that administrators of these systems make some quick changes.
For Configuration Manager:
In order to deploy feature and quality updates to devices running Windows 10, version 1903 or Windows Server, version 1903 (and later), you will need to ensure that you are running the current branch of System Center Configuration Manager, which is version 1902. Then, in the Configuration Manager console, enable the Software Update point to download updates for Windows 10, version 1903 and later and/or Windows Server, version 1903 and later.
If you are using Windows Server Update Services (WSUS) to deploy updates to devices running Windows 10, version 1903 or Windows Server, version 1903 (and later), you will need to select a new product category to sync and download updates. To make this change in WSUS, open the Update Servicesadministrator console, select Options > Products and Classifications, and, in the Products tab, select Windows 10, version 1903 and later and/or Windows Server, version 1903 and later.
Why the change? Per Microsoft:
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. (Note: UUP for on-premises management solutions is not yet available. We will have future news regarding UUP, including a public preview, at a later date.)
