I dont know why name Windows 10 a fail, when the bigger competitors of Windows are... Windows! Mac and Linux mostly are used for niche users (as us). I'm really really happy we CAN upgrade for a new Windows version easily, just compare with Android. More: the reason to most people dont upgrade isn't why "Windows 7 is better than Windows 10", but the actual reason is they are comfortable with Win7 and dont want/can take time to "learn" a new OS. Even Win7 being an awesome OS, took years to take most of XP users (even today there are a lot of loyal XP users out there...)
