Explore exactly what Microsoft 365 is, and why users need it, in this 19-video course, used in preparation for the Microsoft 365 Fundamentals (MS-900) exam. The course offers detailed descriptions of Windows as a Service (WaaS), and its key features and benefits. Learners will hear a practical discussion of Windows 10 updating, and learn more about tools used for assessment and updating. Next, you will receive an introduction to the Microsoft 365 Admin Center, including extensive support information and a mechanism for contacting support directly. Among other key topics covered here are Enterprise Mobility, the Windows Assessment and Deployment kit, and how to configure group policy (with administrator’s privileges) with Windows 10 business editions: previewing builds, feature updates, and quality updates. The concluding exercise allows learners to demonstrate use of the Admin Center, including gaining access, reviewing your subscription, and demonstrating how to add a user; making practical use of Access support; and switching to the Admin Center preview.
