This video will show you how to download games on the Steam PC gaming platform, all while playing a different Steam game on the same PC. By default, setting a Steam game to download and then launching a different Steam game pauses or suspends the download in progress, but by loading your Steam game and then task switching (or minimizing) a launched Steam game (holding the ALT key and pressing the TAB key for example), you can return to the Steam client opened in the background and resume downloading the other game, which allows a download to continue in the background while permitting the user to return (task switch back or maximize) the currently-running (currently opened) Steam game.
