Microsoft released a new preview build to the Slow and Release Preview rings yesterday to belatedly fix the issues in the currently-on-pause Windows 10 October 2018 Update. While we are still waiting for Windows 10 version 1809 to be re-issued, the company continues to work on the next version of the operating system, Windows 10 19H1 slated for a release in Spring 2019.

The company has just started releasing Windows 10 Insider Preview Build 18262 (19H1) to Windows Insiders in the Fast ring and to those who have opted in to Skip Ahead. Since these are very early builds, expect a lot of bugs to be present.
