Running a program is straightforward. It comes straight out of the box with most of the important Windows executables (Paint, Wordpad, Calculator, etc) already added. You can also see that I added Firefox.

Disappointingly it doesn't automatically capitalize the program name if you add it manually. Also dangerously it comes with the registry editor right there in plain sight.

Selecting a program automatically opens it. Upon returning to the command shell, pressing enter redisplays the menu. Pressing escape returns you to the main menu.

And here is a running program.

You can see that even with an added program, it works seamlessly. Pretty outstanding for modern command line stuff!

Removing a program is also automated. It also asks you if you want to remove the program.

Unfortunately, it does not run the uninstaller for the program directly from the shell, instead it wants you to use Add/Remove programs!
Also disappointingly it does this even for system apps which aren't even in add/remove programs...
