Microsoft is now making available Windows 10 build 17758 for devices enrolled in the Slow ring of Windows Insider Program. This is the 34th preview rolling out as part of the October 2018 Update (version 1809), and includes all the same improvements available for the same build number that Insiders received in the Fast ring.
Windows 10 build 17758, according to the company, addresses some issues with the Settings app, Narrator, and nearby sharing not working in certain languages.
Although this flight is now available in the Slow ring, and doesn’t include the watermark in the bottom-right corner, it doesn’t mean that the update has been finalized.
Microsoft make the announcements of Windows 10 Insider Preview build 17758 at the Windows Blog.
