Depends what you want it for, if you want to just remote in now and again, Chrome Remote Desktop is pretty good!
VNC and push out via GPO?
There's a whole ecosystem of free (as in open) software that can do this under the umbrella term VNC (virtual network computing). You might have to sort out your own port forwarding/tunnelling etc. though.
I rate TigerVNC personally.
VNC is fine for internal use, but I wouldn't even consider it over the internet (unless you have some sort of VPN).
