I am not sure what type of program type I need, but I do know that it needs to be a Windows application.
The software needs to perform the following:
Display a button on the bottom right (left) bar that you can click on to toggle the "hide" mode. In "hide" mode the current screens are all minimized (not closed), and a blank Microsoft Excel spreadsheet will open up. Also, the windows task bar on the bottom will be cloaked and will only display "Microsoft Excel" as the open program.
Allow user to configure button(s) that when hit will "Hide Applications" and when another button is hit, it will "Un-hide" the application.
