From November 1, 2020 customers who have purchased Microsoft 365 A3/A5 or Windows 10 Enterprise A3/A5 through CSP can upgrade from Windows 10 Home to Windows 10 Education, and page 42 of the November 2020 Product Terms is updated with this change.

Partners will need to submit a support request to get a Windows 10 Pro Education key which is installed by the customer and then, when the device joins the tenant domain, it is automatically upgraded to Windows 10 Education.
