Can't you just type "Code"? I'm not on a Windows 10 machine at the moment so I can't confirm it there, but it works on Windows 7 and I doubt Microsoft would go backwards in that regard.
Indeed, that works, thank you :) I had previously tried "vscode" and other variations, but it appears the executable name is the super-generic Code.exe. There's still the problem of VS Code opening when I wanted VS, but for this case I'll try to use "devenv" instead.
