Windows 10 & 11 22H2 Rollout and Netlogon Protocol Changes

As we move into the second quarter of 2023, several important patching updates have been released that warrant attention. These updates include critical Windows 10 & 11 changes, Netlogon Protocol and more. Here are the key updates from April.

Windows 10 & 11 22H2:

Feature Update version 22H2 for Windows 10 and 11 is in its final rollout phase. Microsoft is offering this update to an expanded set of eligible devices running Windows 10, version 20H2, and later versions​. We at OneNeck recommend updating your devices to ensure future security updates install on your systems. This upgrade is not automatic via standard patching, so manual installation is necessary.

Devices that utilize BitLocker require a manual update to the Windows Recovery Environment for Windows 10 & 11. We recommend manually applying this update wherever applicable. If you have questions about how OneNeck can assist you with these processes, please contact the Service Desk.

Netlogon Protocol Changes – CVE-2022-38023:

By July 2023, the ability to set the Compatibility mode setting will be removed​.
