It is a retail digital license. It did say Retail on that screen, and the last 5 digits is the generic key's last 5, when those two go together, it indicates digital license. This is typically seen for those users who claimed free upgrade from Windows 7/8 to windows 10. That's why I asked that previous question.
Since your account is the one using the computer now and the license is activated on this, it is currently linked to your account. Unfortunately there's no way to tell who it was linked to before this, if there was any.
There's no issue from the look of it at all, I just cannot tell how you got it, but I can tell you with confidence that there's no issue with this license.
