Two long-standing issues are provisioning packages not working as expected and copying large files of several gigabytes (GB) takes longer than expected on SMEs.

Along with this update, Microsoft is also warning that Windows Server Update Services (WSUS) servers may not serve Windows 11 22H2 updates released on or after February 14, 2023.

“Updates released on February 14, 2023 or later may not be offered by some Windows Server Update Services (WSUS) servers to Windows 11, version 22H2. Updates will be downloaded to the WSUS server but may not propagate further to client devices.”

“WSUS servers affected are only those running Windows Server 2022 that were upgraded from Windows Server 2016 or Windows Server 2019.”
