Build me a simple Windows remote desktop app for my own machines, with a small client and a main app that can connect to it and show the screen. I want it to feel lightweight and work on a few different Windows versions, since I may use older systems too.

Make it easy to start, connect, and see the remote screen clearly, with basic controls for mouse and keyboard. If you need to check current Windows or C++ docs online, go ahead. Please keep the setup straightforward so I can open the solution and run it without a lot of extra work.
