What you propose seems nice but is infeasible. Lightweight doesn't just mean getting rid of Paint3D and all this cruft installed by default. Today you have tons of APIs and services that need to be running, otherwise X breaks. The X could be your Bluetooth audio connection, and app that uses an obscure API call, a network service etc. So basically your lightweight alternative would be a broken, less powerful copy of Windows 10. So at that point it's just safer to use an older combination of OS and software that you know has been working fine.
