Final answer:
To quicken GPO processing for a GPO that contains only computer settings, enable 'Turn off user settings' within the GPO. This results in faster application of policies and reduced login times by skipping unnecessary user settings processing.
Step-by-step explanation:
When you create a Group Policy Object (GPO) that contains only computer settings and not user settings, you can speed up the GPO processing by enabling the policy setting 'Turn off user settings'. This setting is found within the GPO itself under Computer Configuration, Policies, Administrative Templates, System, Group Policy. By enabling this, the system will skip the processing of user settings since the GPO does not contain any, which results in reduced login times and faster application of GPOs to the clients.
In addition, you can also ensure that the GPO processing is streamlined by regularly reviewing and cleaning up any outdated or unnecessary GPOs, and by using WMI filtering only when necessary as it can add overhead to the processing time. To further enhance the process, make sure the Active Directory infrastructure is optimized and that domain controllers are well connected with low latency network connections.
