WINDOWS key to escape game

Playing games "Civilization 4" and "Company of Heroes Legacy Edition" downloaded via Steam. This question has also been posted to the Steam forums.

Thank you for taking a look.
Using Windows 7 64 bit and latest Google Chrome Browser.

While playing, I am sometimes able to exit the game by simply pressing the "windows" key on my keyboard. This brings me to the desktop, where I usually have a video streaming paused.
I like to go back and forth. Unfortunately, this frequently will not work. I am posting to ask for a workaround to FORCE this to always work.
I sometimes try Windows + D, and that is not any more reliable.

I don't play those games but this is all the keyboard shortcuts for the first-

Civilization IV: Keyboard Shortcuts | CivFanatics

I don't see where using the "Windows" key is mentioned.

I find pressing ALT + TAB keys a quite reliable way of Exiting any game. Some games use those keys for the in-game inventory, so you may need to configure the in-game keyboard configuration for the shortcut to function as a system command. Also, you may experience a delay before the effect takes place, this delay is usually down to available physical memory. To continue the game, press ALT + TAB again. Pressing Windows Key + TAB also works well in the same situation.

To get shrink the game to do something on the internet or something you can pause your game and click Alt + Tab. Then you will go to your desktop and the game is just shrunk.
