Got a few questions about windows 10 if anyone has answers firstly I reserved windows 10 to my pc and laptop but had problems with the pc so I factory reset it which failed so I had to clean install it from the site I previously had an activated version of windows but this time I had to skip the product key activation as I didn't have one now I get a message at the bottom right of the monitor telling me to update the windows product key so will my windows 10 eventually stop working if I don't pay £99 for an activation key that I already had for free? secondly I know the activation key for my laptop which is also windows 10... If I put the laptop activation key into my pc and used them seperately would microsoft a multi billion dollar company care that I am using the same activation key for two devices and stop me anyway
