These days Microsoft is heavily reliant on diagnostics data to ensure Windows 10 is humming along nicely across the world, and key to this ability is Release Quality View (RQV), an internal dashboard Microsoft uses to assess the ongoing health of millions of systems before and after updates roll out.

So while Microsoft does depend heavily on diagnostic data, the pair of data scientists emphasize the internal checking by engineers that takes place even before Windows Insider testers receive a build.
