Part of this confusion is we seem to have two new threads that talk about the same KB under different conditions and purposes. It can't be Stable build and Insider Slow at the same time. The only build with 15063 in it that is close to Insider is the Release Preview Ring, which has had no updates at all since CU was released.
This one here: Cumulative Update KB4022716 Windows 10 v1703 Build 15063.447 - Windows 10 Forums
And this one:
