Improvements
This security update includes quality improvements. Key changes include:
-
Enforces a hardening change that requires printers and scanners that use smart cards for authentication to have firmware that complies with section 3.2.1 of RFC 4556. If they do not comply, Active Directory domain controllers will not authenticate them. Mitigations that allowed non-compliant devices to authenticate will not exist after August 9, 2022. For more information about this change, see KB5005408.
If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.

To mitigate this issue, please see Possible issues caused by new Daylight Savings Time in Chile. We are working on a resolution and will provide an update in an upcoming release. Note We plan to release an update to support this change; however, there might be insufficient time to properly build, test, and release such an update before the change goes into effect. Please use the workaround above. |
After installing this update, file copies using Group Policy Preferences might fail or might create empty shortcuts or files using 0 (zero) bytes. Known affected Group Policy Objects are related to files and shortcuts in User Configuration > Preferences > Windows Settings in Group Policy Editor. |
This issue was addressed in KB5018425. Installation of this update prevents and resolves this issue, but if any workaround was used to mitigate this issue, it will need to be changed back to the original configuration. |
