windows 10 installation, you have to understand how the Windows-10 activation works: If you have performed an upgrade of Windows 7 or Windows 8 for the first time on a PC, Windows 10 based on your installed hardware components created a PC identification number, the so-called machine ID. This is unique. The machine ID is transmitted to the Microsoft server and stored there. Then Windows 10 about the server is activated. You don’t see a Windows 10 key here.
If you installed later on the PC Windows 10 completely new, you need to enter more a key, because the operating system on the PC was already installed and enabled during installation. The Microsoft servers recognize so again sent machine ID, that this already exists and automatically activate Windows 10 after installation via the Internet.
