Windows 10 build 18237 (19H1) is now available for Skip ahead Insider members. The new build has added a long list of changes and improvements as well as new acrylic, a type of brush from the Fluent Design System, to the sign-in screen background. In addition, the build has fixed an issue where Narrator would incorrectly report some standard combo boxes as “editable combo box” instead of “combo box”. Check out more details below.

What’s new in Build 18237

Bringing acrylic to the Windows sign-in screen

Added acrylic, a type of brush from the Fluent Design System, to the sign-in screen background. The translucent texture of this transient surface helps you focus on the sign-in task by moving the actionable controls up in the visual hierarchy while maintaining their accessibility.

Showing the login screen, where the background image now has an acrylic effect applied to it so it’s blurred.

Known issues in Build 18237

  • Narrator sometimes does not read in the Settings app when you navigate using Tab and arrow keys. Try switching to Narrator Scan mode temporarily. And when you turn Scan mode off again, Narrator will now read when you navigate using Tab and arrows key. Alternatively, you can restart Narrator to work around this issue.
  • You may notice the background of notifications and the Action Center lose color and become transparent (with an acrylic effect). We’re aware that for notifications this can make them difficult to read and appreciate your patience as we work on a fix.
  • If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.
