Hey! Gimme some help here

Heavy on the suspension of disbelief, 'K? Time travel. You're transported to 2105. (Yeh, yeh, forget the lil problem of WHERE in space the Earth will be then—as the Milky Way expands at about a million miles a day—just go with me, 'K?). You discover that no one's heard of a company called Microsoft and the idea of Windows is completely foreign to people alive in 2105. So, tell me, what happened to Microsoft and to Windows? Make it real, folks... :-)
