I don't know anyone who has used a computer, who hasn't worked on a Windows platform. And I'm sure even you don't.
And therefore, I hope you people know that there's a game Solitaire in your PC. Ever wondered in the era of NFS, COD and CS, why the hell is that game in your beautiful PC ?(no offense to solitaire lovers, but I think that game is better with cards in your hands.)
Well the Microsoft has your answer with a stupid reason.
The game solitaire was ACTUALLY inculcated in in your system to teach you DRAG AND DROP technique.
As stupid as that.
