Hi, @Tyler ,
When you registered your PC with Azure AD following the steps mentioned, did you check the "Join this device to Azure Active Directory", or did you just fill in the field asking for the email?
Please note in the attached documentation that when we are going to register a PC already configured in Azurre AD we have 3 options:
1 - Put the direct email in the requested field: when we perform this action, the PC is registered in Azure AD as a Registered Device.
2 - Further down, in Alternative Actions we have the option "Join this device to Azure Active Directory": This is the correct option that we must select when we want the PC to be registered in Azure AD as Joined Device
3 - The third option is to register the PC in the AD on-premises
Paragraph 3 of the document shows a screen of the correct option for Joined Devices
