Microsoft operating systems such as Windows 10 have an activation system that allows you to "legalize" your OS. Basically, activation consists of registering a product key, so each operating system has a unique product key that will help you register your Windows 10 and thus access all the functions of the operating system in a legal and legitimate way. Obviously to acquire this product key you must pay for the Windows license. But what happens if when activating or updating you receive the error 0xC004F012?
