Something big always happens to Microsoft in October, and there’s a reason why

If you line up every major Windows release since 1991, something odd jumps out. Windows XP, Windows 7, Windows 8, Windows 11: all launched in October. Microsoft shipped its first Office suite for Windows in October. The first Surface tablet? October. And Bill Gates himself was born on October 28. It looks like luck, but it’s strategy. Microsoft has a very specific reason for stacking its biggest launches into one month.
