I have Pi3 model B running Windows 10, I also have a laptop running Windows 10. I want to start the remote server in Pi3, via code, because I don't have an HDMI display. Is this possible?
Yes sure, you can isntall the Windows IoT Remote desktop client on your Windows 10 machine from the app store
Then you will see on your Windows 10 desktop the exact screen as it would be on HDMI
