This critical alert is provided by HeliX to make you aware of important information regarding your Operating System or its embedded components. See below for additional details related to this issue.
The “PrintNightmare” vulnerability announced recently is exposed by a flaw in the Print Spooler service. An out-of-band update was released by Microsoft to address this flaw and the fix was subsequently added to the July Cumulative Update for Windows 10. However, these updates will not install on unsupported releases of Windows 10. To mitigate the issue on devices running an older, unsupported version of Windows, the only option is to block remote printer connections and restrict the installation of printer drivers via Group Policy and/or the appropriate registry values. Please refer to the KB articles below for more details. Administrators running supported releases of Windows 10 should install the update as soon as possible and also follow the Microsoft guidance on configuring Point and Print restrictions.
