I use shortcuts heavily, but Win+number is something I never get used to despite knowing them. They way they work when you have multiple X programs opened (say, editors, explorers..) is kinda weird and I ended up just using alt+tab, which is much easier to press anyway.

Microsoft's PowerToys has a shortcut guide that might help get you over that last hurdle towards using win+number effectively. Might want to give it a look.

Taskbar Numberer [1] can do this as well (under Window 10). Startup command is

    start "" "<apps>\7plus-Taskbar-Numberer\64\7+ Taskbar Numberer.exe" -v2 -hidewnd

Yes, I use them for launching "singleton" applications, and Alt+Tab for the rest.
