I am not overly concerned, but when it comes to drivers I would prefer having control over which drivers are installed. I predict that Microsoft may correct this in the future. We shall see. So there is no suitable poll answer for me. I care, but I am not angry or worried.
O&O Shutup10 allows you to disable driver and Windows updates. I have not tested turning off updates in it yet. I may disable the driver updates only for now. No reason for me to disable actual Windows updates.
