Microsoft has confirmed something in the latest cumulative updates shipped by the company for Windows 10 devices.
The Redmond-based software giant says the July 2021 cumulative update might cause printing and scanning to fail on some devices which use smart-card authentication.
“After installing updates released July 13, 2021 on domain controllers (DCs) inside your environment, printers, scanners, and multifunction devices which aren’t compliant with section 3.2.1 of RFC 4556 spec, might neglect to print when using smart-card (PIV) authentication,” the organization explains.
Microsoft says the bug exists in most cumulative updates which were shipped to Windows 10 devices as part of the July 2021 Patch Tuesday cycle, and while the organization adds that it’s already working on a temporary fix, you should always make sure that you are using the most recent firmware and drivers readily available for our device.
Temporary workaround coming
“If your firmware and drivers are up-to-date but you just encounter this issue, we recommend that you contact the device manufacturer. Inquire if an environment or configuration change is needed to bring the unit into compliance using the hardening change or maybe a compliant update will be available,” Microsoft says.
Meanwhile, devices with PIV authentication and influenced by this glitch will be able to stick to password authentication, which should still work properly even after installing the latest cumulative updates.
“We will work on the temporary mitigation and will offer an update soon. This temporary mitigation should allow printing and scanning to the affected devices. This will allow here we are at device manufacturers to release compliant firmware and drivers for their devices. Further, it ought to allow time for you to update settings, firmware, and drivers inside your environment and make them compliant,” the company notes inside a technical description from the problem.
