The Override print driver execution compatibility setting reported by print driver machine setting should be configured correctly. This policy setting determines whether the print spooler will override the Driver Isolation compatibility reported by the print driver. This enables executing print drivers in an isolated process, even if the driver does not report compatibility. If you enable this policy setting, the print spooler will ignore the Driver Isolation compatibility flag value reported by the print driver. If you disable or do not configure this policy setting, the print spooler will use the Driver Isolation compatibility flag value reported by the print driver. Fix: (1) GPO: Computer Configuration\Administrative Templates\Printers\Override print driver execution compatibility setting reported by print driver (2) KEY: HKLM\Software\Policies\Microsoft\Windows NT\Printers\PrintDriverIsolationOverrideCompat
