Your example for "Setting up Remote Desktop" (https://www.dynu.com/Resources/Tutorials/DynamicDNS/RemoteDesktop)
uses Windows 10 Professional.

Unfortunately, I only have Windows 10 Home, which only includes Remote Assistance and not Remote Desktop.

Do you have any other suggestions for connecting remotely to my Windows 10 Home PC?

You can upgrade to Professional anytime but it consts you money of course.

As an alterntive you can use VNC.
