It started in Vista, AFAIK, but it didn't really become reliably useful for _most_ of the drivers on even relatively common hardware configurations until 7, and even now it's still not complete (I installed a Coffee Lake-era Intel desktop with Win10, and I still got to play Hunt the Unknown Device Driver even after the endless reboots for updating had installed every driver Windows Update offered, and that's for onboard peripherals, not a fly-by-night USB device or PCIe card.)
