Microsoft originally put Solitaire into Windows to keep people from being intimidated by the operating system. It gave users something familiar to do while learning to use a mouse.
When you slow down the Windows-95 startup sound by 4000%, it becomes 2.5 minutes of dreamy, ethereal, ambient music.
Solitaire was created by a Microsoft intern who wasn’t paid for the game. Bill Gates liked the idea but complained it was too difficult to win at this game. Original version also included a fake Excel spreadsheet to hide the game from your boss.
