Hi , I just want to understand how legitimate is the phone activation method for activating Windows 8 ( with Keys that are blocked for online activation ) . Is this some sore of a loophole that we are exploiting ? Also , One activated using phone activation , would the key used for phone activation be the key for my Windows installation , or the key changes ? Would this key work while downloading Windows 8.1 using the product key as well ? Can someone shed some light ?
