Suggest a remote desktop program?

TL:DR: Need a remote desktop program that will let me get into my desktop from another network with no action required at the desktop itself.

Will be out of town for about two weeks, have a Windows 10 desktop and a Windows 10 tablet. Desktop stays home, tablet is going with me in case I need something from my desktop. Need a way to connect and access and control my desktop from the tablet (I'll have KBM with me) with no interaction at the desktop itself (most remote desktop programs require confirmation at the desktop to access and/or gain control).

Suggestions? FOSS preferred.
