Windows 11 Insider Preview Build 23430 – Changes and Improvements

  • General
    • Urgent or important notifications that break through when do not disturb is turned on while using apps at full screen will now display a “view notification” button to view the content of the notification for privacy.
    • In the previous flight, we documented that Content Adaptive Brightness Control (CABC) works on desktop PCs – however, it does not. We have updated that blog post. Content Adaptive Brightness Control (CABC) also needs to be enabled by the OEM (the manufacturer of the device). As a result, this feature is not available on all laptop or 2-in-1 devices.
  • Settings
    • A limit of 20 most recent tabs has been introduced under Settings > Multitasking to show tabs in ALT + TAB and Snap Assist.
  • Developer
    • We are introducing a new setting under Settings > Privacy & security > For developers to enable end task when right-clicking an app on the taskbar. This setting is in Build 23430 but does not currently work when the feature is toggled on. It will be fixed in a future flight.

    • Fixed an issue where the buttons in the Pinyin IME’s settings flyout were hard to see when they had focus if a contrast theme was enabled.
  • Task Manager
    • Fixed an issue impacting Task Manager reliability.
    • The search box should no longer be cropped at the top when the window is maximized.
