Microsoft is continuing to roll out new Windows 10 19H1 test builds with today’s Build 18290, which went out to Fast Ring testers. There are still no major new features in 19H1, but the latest test build adds more UI tweaks and polish, along with a bunch of fixes.
As part of today’s build, Microsoft is adding an orange indicator to the Windows Update icon in the notification area (system try) which is meant to alert users when they need a reboot.
