i want to reset my windows 10 anniversary update to factory setting,so i'm gonna to lose my License key or not? thank you
Yes, like LatinMcG said, activation works off your hardware ID's. Even if you were to clean install, once you go on the Internet it would activate. You just have to reinstall the same version of Windows you have now (Home or Pro). Activation is good for the life of the PC. The only time you may lose activation is if you replace some major components of your computer, like the motherboard. Now you can link your license to your Microsoft account so you may not even loose it then. I'm not really sure how that's going to work.
