Microsoft has finally started sending some new features and improvements to Skip Ahead Insiders after quite a long wait. The company is concurrently giving the finishing touches to Windows 10 October 2018 Update. As noted previously, Skip Ahead Insiders have been moved to testing the 2019 edition of Windows 10 – aka Windows 10 19H1.

Today’s build brings the first set of features that aren’t being rolled out to the Fast Ring Insiders who are on the upcoming version of Windows 10 expected to be released in October. All of these are focused on Narrator Improvements along with some general bug fixes.
