Win10 Keyboard Shorcut to Calculator?

I made a shortcut on my Desktop to %WinDir%System32calc.exe. This shortcut had the normal right-click, Properties with our Shortcut key friend!

If I placed the shortcut in %WinDir%System or Documents it seemingly wouldn't work!? It was flakey even moving back to Desktop, but after I set the shortcut to something else, hit Apply, then back to Ctrl+Shift+C it'd work :P
