I think you replied to the wrong message. I'm not sure who you were talking to. Anyway, I've moved this to the forum I think most appropriate.
I tried the Docker Pull you mentioned under Linux and it works just fine. From the looks of it, something is doubling up doing a pull in Windows, since I'm pretty sure that those "%2F"s are escapes for slash characters.
I'd think that the pull should be using https, not http, but neither one will work if it generates a bad URL.
The ultimate cause your problem, however, is most likely that you're doing a "docker pull" from a non-administrative user account. You need to do the Windows equivalent of "sudo". Which is probably most easily done using the Windows menu to open an administrative account command window. Details of which may vary depending on what version of Windows you're using. Of course.
"privilege" comes from the Latin words for "private" and "law" (legal) and dates to feudal times. To "claim privilege" meant that you were above the laws that applied to the common people.
