Many of the world's largest companies still run Windows and are heavily invested in it. Also, many admin tools (even for Unix-based services) are written for Windows, because IT admins have to straddle both worlds.

Also, for all its ills, Windows is not a bad platform for most lay users. Yes, of course we've all been bitten by it, but if all you need to do is normal office work, it's not bad.
