Security News > 2022 > July > Microsoft warns that new Windows updates may break printing

Microsoft warned that starting with this week's optional preview updates, temporary mitigation provided one year ago to address Windows Server printing issues on non-compliant devices will be removed, potentially breaking printing.

As Redmond explained last year, a known issue might cause print and scan failures on multiple Windows Server versions after installing the July 2021 security updates on Windows domain controllers.

On Thursday, Microsoft said that the temporary fix has now been disabled by this week's optional preview updates on Windows Server 2019 systems.

"Starting on July 21, 2022, this temporary mitigation will not be usable in security updates. The Windows July 2022 preview update will remove the temporary mitigation and will require compliant printing and scanning devices," the company said in a Windows message center update.

"All updates released on this day or later will be unable to use the temporary mitigation," Microsoft explains in an updated support document.

To find non-compliant devices that will fail authentication after installing July 2022 or later updates on Windows DCs, admins should check logs on their Active Directory DCs for audit events identifying RFC-4456 incompatible printers added after deploying February 2022 Windows Server updates.
