I use sunshine/moonlight there is nothing as good as that.
Both the server and client run in portable mode
By default it will fullscreen and use relative mouse but use this command line to one-click start moonlight
Moonlight.exe --display-mode windowed --absolute-mouse --resolution 1920x1080 stream yourserver.lan desktop
Only little hiccup, the client need to pair with server before connecting, the client will give you a number and you type it in the sunshine management interface
