Unable to deploy W10 > W10 19XX (Feature Updates) to Windows 10 Clients via WSUS on Server 2012 R2.

That is a patch you need to Update your W10 client from W10 19XX to 19XX/20XX via WSUS.

This should have been fixed by Update KB 2919355 and Windows8.1-KB3095113-v2-x64. However on some WSUS Server 2012 R2 we could not install the patch (Depending on the order you installed Patches and installed the WSUS role timely). The patch does open the handling of ESD files in the Web server IIS (So the IIS know what to do with the Extension and how to Deliver it). You can manually add that entry in IIS.

Error you see in WSUS Server

Close and maybe restart IIS or best WSUS Server.

After reboot of the WSUS you that the clients download the update.
