Ok so I was playing a game the other day, and I needed to go back to my internet browser alot, but the game wont let me minimize it, and it doesn't have the ability to make it windowed in the options, or with the -window command. I was wondering if any one knew of a program that would either let me make fullscreen games/programs run windowed, or have a window that I could like run the game inside that would make the game become windowed... let me give an example

(click on that image to make it bigger) As you can see in the picture, calc.exe is inside the notepad, pretend notepad is the program I'm talking about, and calc is a fullscreen game, well you run notepad(the windowed maker) and when you open you hit a button and a box opens, and you goto the .exe of the fullscreen game, and double click on it. The game now loads inside of the notepad(windowed maker program). I hope I am not confusing anyone.
