HH, After continued playing I'd have to say that the easiest way to get something back that's similar to the classic calculator, but that runs under Windows 10, it's definitely downloading and installing Microsoft Calculator Plus. When initially installed the default view does not look like the good, old fashioned calculator, but it's easy to make it look exactly like that if you wish. It has a View menu and the first thing that I did was switch to standard view (I think it started out as scientific). Then, afterward, in that same View menu, there is an toggle option at the bottom, "Classic View," which makes it look exactly like the old calculator. Even if you change nothing about the appearance, the old Ctrl+C when you've completed a calculation copies the result to the clipboard and you can paste it elsewhere.
I tried testing the old Win7 calc.exe program that I copied over to my Win10 machine, and it will not run even when Windows 7 compatibility mode is used. Microsoft Calculator Plus runs perfectly, and gets back the function that you seem most interested in having. Brian
