Hi @Patrik Silverby ,
As you correctly mentioned, Windows 10 Home cannot be joined to a domain. This is documented in the feature comparison guide between Windows 10 Pro and Windows 10 Home. You can, however, use Intune, or upgrade to Windows 10 Pro.
In order to sign in to Windows with a corporate user account, the Windows 10 device must be joined in Azure AD, which is not supported for Windows 10 Home edition.
For this reason, it's not possible to sign in with corporate account instead of local user account.
That said, you still can manage the Windows 10 Home edition device by using Intune, or by upgrading to Windows 10 Pro.
