We fixed an issue that could result in certain UWP apps silently terminating when minimized.
We fixed an issue resulting in certain devices with BitLocker enabled unexpectedly booting into BitLocker recovery in recent flights.
We fixed a race condition that could result in the taskbar not autohiding after opening and closing the Start menu while a fullscreen window was visible.
We fixed an issue where typing in Start would switch to a blank Cortana screen if Start was open when the PC went to sleep.

Sometimes having too many choices can be confusing and less is more. That is why this new build has consolidated the places where users can adjust their display brightness by removing the display brightness slider in Control Panel Power Options and the “Display brightness” section under Power Options Advanced Settings. Don’t worry! You can still adjust your display brightness via Settings > System > Display settings, the Action Center, and via keyboard hot keys.
