Without explanation, Microsoft has removed the just-released November update (version 1511) from the download page it offers to the general public. The media creation tool now downloads the initial release of Windows 10 instead. [Update: Microsoft tries to explain.]

. . .
Update: The version 10586 Media Creation Tool is still available from an unpublished link on Microsoft's download servers. Microsoft will probably remove it before long, but for now at least it works to upgrade systems running the original (build 10240) release of Windows 10 or to create a version 1511 ISO file.
