Ahead of the 19H1, and even before the 19H2 release, Microsoft is now rolling out Windows 10 build 18850 for PCs enrolled in the Fast ring with the Skip Ahead option. This is the fourth preview available to testers as part of the 20H1 development arriving in spring 2020, and while it doesn’t include new features, the update delivers several fixes and improvements for the Snip & Sketch experience.

Windows 10 build 18850, according to the company, fixes problems with Narrator, Windows Sandbox, Lock screen, Start menu, Microsoft Edge, and it also include changes to improve syncing reliability with the cloud clipboard experience.

As part of the Snip & Sketch changes, build 18850 addresses a problem that resulted on snips being a bit blurry after saving or copying to clipboard

Resolves an issue where copying to clipboard would fail if you switched out of the app while the copy operation was in progress. Fixed an issue where auto-copy changes to clipboard wasn’t working. And now, the experience includes Narrator (screen reader) confirmations when a snip is copied to clipboard.

The company explains that some features need a longer lead time, but once the April 2019 Update releases, devices in the Windows Insider Program will resume getting builds for the 19H2 development.

Alongside the new improvements, Microsoft is also announcing several known issues for Windows 10 build 18351 at the Windows Blog.
