Yesterday, Microsoft released multiple Windows updates to fix the widely reported “PrintNightmare” vulnerability in the Windows Print Spooler service.
According to Microsoft, this vulnerability is impacting all Windows 10 versions, including the most recent May 2021 Update (version 21H1) and version 20H2 (October 2020 Update).
To deploy Microsoft’s patch, you need to check for updates under Updates & Security > Windows Update and apply the latest July update, and reboot the system when prompted.
