Windows Update is getting better at saving your PC from buggy drivers

Hardware driver updates can be a blessing and a curse. When they're good, they can fix bugs, improve performance, and add new capabilities, giving your PC a minor upgrade without requiring any extra effort or investment. When they're bad, they can make a once-reliable PC slower and unstable, handing you a one-way ticket to blue screen town (or whatever color the Windows error screen is these days ).
