Why does my Windows 10 Home have Remote Desktop?
Solution 1:
You have the Remote Desktop client. That comes with all editions of Windows that I'm aware of. Therefore, you can remotely log into to other machines that support it. Your computer does not, however, have the server part of Remote Desktop, so you can't remote into your machine from anywhere else. The server part only comes with Pro and Enterprise editions of Windows (and the Windows Server OSes).
