What does this do?
This may be obvious for some but I have had enough questions to post it. You can add your organization’s name or message for deployments (see screenshot) under the Computer Client Agent Properties found within Site Management\Site\Site Settings\Client Agents. This is not like a company logo but it still ensures that your End-Users know that the deployments are coming from IT.
