Windows 11 and OS-tan

META

Windows 11 did not get an official OS-tan. Windows Navi+ did not ship a sequel after Tōko. Microsoft Japan did not announce a Madobe for 11. Everything you have seen is fan work plus one social-media mixup.

Wikipedia's Windows 11 subsection is useful for the negative claim and for the Instagram date. It is weaker on 11-chan. This page exists so the negative claim has a URL.
