Execute print drivers in isolated processes

This policy setting determines whether the print spooler will execute print drivers in an isolated or separate process. When print drivers are loaded in an isolated process (or isolated processes), a print driver failure will not cause the print spooler service to fail.

If you enable or do not configure this policy setting, the print spooler will execute print drivers in an isolated process by default.

If you disable this policy setting, the print spooler will execute print drivers in the print spooler process.


Notes:
-Other system or driver policy settings may alter the process in which a print driver is executed.
-This policy setting applies only to print drivers loaded by the print spooler. Print drivers loaded by applications are not affected.
-This policy setting takes effect without restarting the print spooler service.
