Windows 7 Calculator – how to make it stay on top always

I’m use the Windows 7 built-in calculator from time to time, and when I use it, I want to make it stay above all the other windows, so I can see the numbers and copy them, etc to other applications. How can I do this?

Other than putting the windows side-by-side please.

Thanks!

As listed in this answer for another question. You can use autohotkey which is loved by a lot of users.

Toggle the active window topmost status (always on top):

      WinSet, AlwaysOnTop, Toggle,A
