Windows 10 requires activation to verify you're running a genuine copy; a unique product key is used to ensure the a single licensed copy of Windows isn't being used on more than are allowed.

MS has not 'blocked' your key, because it's a generic key issued to every single Windows 10 upgrade. It's useless, and you cannot use that key for anything. When you try to use that key, it says it's blocked because the key cannot be used that way. I did the Windows 8.1 to Windows 10 upgrade and activated Windows 10 successfully. I then downloaded the media creation kit, created a bootable USB and did a fresh installation of Windows 10. This second installation would not activate and told me the key had been blocked.
