As of Sept. 9, Minecraft Windows 10 beta is identical to Pocket Edition. Most questions regarding either pertain to the other, with the exception of minor technicalities such as savegame location (which are already there within the PE tag).
Back when the Windows 10 version was one patch ahead of PE, I created minecraft-windows-10, with the full intention to synonymize later. The time for that is now.
While simply re-tagging the 3 questions with that tag to minecraft-pocket-edition would work, I suggest a synonym, since the Windows 10 edition is, and likely will remain, branded as "Windows 10 edition", rather than PE.
