You have finished the creation of the QoS GPO.
But, you still need to enable the use of your new Group Policy.
On the Group policy management screen, you need to right-click the Organizational Unit desired and select the option to link an existent GPO.
In our example, we are going to link the group policy named QOS - LIMIT HTTP 50KBYTES to the organizational unit named QoS.
After applying the GPO you need to wait for 10 or 20 minutes.
During this time the GPO will be replicated to other domain controllers that you might have.
After waiting 20 minutes, you should reboot the QoS client computer.
During the boot, the computer will get and apply a copy of the new QoS group policy.
After rebooting the client computer, open a POWERSHELL command prompt.
Use the following command to check if the QoS group policy was applied.
