Based on the output from the data set above, the client is configured to allow users to configure Automatic Updates.
For this client, Automatic Updates are configured with AUOptions=4 which means to install updates on a scheduled day and time.
When Automatic Updates is set to "not configured," as it appears to be here, the following occurs:
"If the status is set to Not Configured, use of Automatic Updates is not specified at the Group Policy level. However, an administrator can still configure Automatic Updates through Control Panel."
For Configuration Manager clients, we recommend that Automatic Updates be disable to avoid unexpected reboots since AU can come online and check for residual work such as pending reboots and invoke the reboot outside Configuration Manager.
