That hasn't been true for the vast majority Enterprise environments for the last decade or so, and even before for places which dumped the the Windows 9x lineage earlier. Even home users on anything beyond XP rarely run with default Administrator privileges anymore, although they're still a click away for most users, through UAC. Curiously enough, while Linux power users frown upon running as root, in Windows it's usually the power users who choose to disable UAC, although it's less bothersome than sudo (no password needed).
