The Find vulnerabilities and required updates and Install required updates and fix vulnerabilities tasks are created automatically, if you do not have ones.
In the Windows Server Update Services group of settings, you can select the update synchronization method:
Client devices will download Windows Update updates according to your domain policy settings. Network Agent policy is created automatically, if you do not have one.
Client devices will download Windows Update updates from the Administration Server. The Perform Windows Update synchronization task and Network Agent policy are created automatically, if you do not have ones.
If you prefer not to run the Quick Start Wizard, create the Find vulnerabilities and required updates and Install required updates and fix vulnerabilities tasks later. To use Administration Server as the WSUS server, create the Perform Windows Update synchronization task, and then select the Use Administration Server as a WSUS server option in the Network Agent policy.
