Windows Update will now alert Windows 10 users when a featured update is blocked from being installed. Microsoft has made it so Windows 10 will explain that the update is available, but that it is being blocked on their computer for some reason. Users who are using certain older bluetooth drivers, older versions of anti-cheat BattleEye software, certain AMD Raid drivers, or even certain Intel drivers, will not receive the update due to conflicts. The change is much better than the previous way of just not showing anything at all.
