I use this: https://winaero.com/blog/get-calculator-from-windows-8-and-w...

I don't know if it has the features you're missing, I use it because I don't like the look and feel of the new apps.

Very nice, and it even has a chocolatey package via choco install oldcalc so I can do my [Windows]+R calc and have the Win8 calculator open, very nice indeed!
