Hey guys, So my question is that i used Windows installation media tool to make a copy of win10 on an usb flash drive, During installation i choosed windows 10 pro to be my version, as i was going to buy a key and activate it, but after installation, i opened my computer's properties to see that the windows is already activated, putting in mind, i didn't activate anything, it has just been formatted, and when i opened activation window inside settings tab, it said "windows is activated with a digital license linked to your microsoft account", So can anyone please explain how is it activated?
