Windows 10 allows you to join your computer to the Azure Active Directory and login with your cloud credentials. The first account that joins the AAD becomes a local administrator. Subsequent users are not.
To add additional azure accounts as local admins you need to do the following…
- Open a command prompt with Administrator proviledges
- Enter the following command…
net localgroup administrators /add "AzureAD\<users office 365 email address>"
You should see “The command completed successfully”, now go check it worked by going into computer management > Local Users and Groups > Groups > Administrators and check to see if the user is listed.
