Hi my windows 11 laptop keeps updating with KB5089573 (26200.8524), I then need to use bitlocker recovery key (4 times). The most annoying thing that my date/time/notifications/wifi shortcut from the bottom right has disappeared once windows removes the update (I've tried getting it back from taskbar/notifications settings)

    KB5089573 is an optional preview update, it is basically an early beta release of the June update released in May.

    The optional preview updates can be hard to install sometimes, may contain bugs and there is no need to install the optional preview updates.

    If you have uninstalled that update to resolve the problems it caused, below that update is a switch to 'Get the latest updates as soon as they are released', disable that option and restart your PC, that will stop the optional preview updates installing.

    If you have now uninstalled that update, are you still experiencing the problem with the System Tray icons at the far right of your taskbar being missing?

    If so, do you have any customization app like WindHawk installed on your PC?

    KB5089573 is the update that resolves a known issue where earlier Windows 11 24H2/25H2 builds could fail to install security updates with error 0x800f0922 when the EFI System Partition (ESP) had very little free space. The context only documents that this update fixes that ESP/0x800f0922 problem and that, if installed, no additional workaround is required. It does not describe crashes, repeated BitLocker recovery prompts, or loss of taskbar/date/time/notification area after rollback.

    From the available information, only the following supported actions are documented:

    1. Ensure KB5089573 or later is fully installed
    • For Windows 11 24H2/25H2, installing KB5089573 or any later cumulative update is the recommended resolution for the ESP-related update failure. Once this update is successfully installed, the specific 0x800f0922/ESP issue should no longer occur.
    1. If KB5089573 is failing to install because of ESP free space If the device is actually failing to complete KB5089573 due to low ESP space (symptoms include rollback around 35–36% and error 0x800f0922 in CBS.log), the documented workaround is:
    • Workaround 1 – Adjust ESP padding via registry
      1. Open Command Prompt as Administrator.
      2. Run: 
             reg add "HKLM\SYSTEM\CurrentControlSet\Control\Bfsvc" /v EspPaddingPercent /t REG_DWORD /d 0 /f
      3. Restart the device.
      4. Retry installing the update.
      Warning: Editing the registry incorrectly can cause system issues. A registry backup is recommended before making changes.
    • Workaround 2 – Known Issue Rollback (KIR)
      • For consumer and non‑managed business devices, the KIR mitigation is delivered automatically. Restarting the device can help the rollback policy apply faster.
      • For enterprise‑managed devices, IT admins can deploy the KIR Group Policy package for Windows 11 24H2/25H2:
        • Install the MSI: KB5089549 260514_06221 Known Issue Rollback for Windows 11 24H2/25H2 and Windows Server 2025.
        • Configure the corresponding Group Policy under Computer Configuration > Administrative Templates as described in the KIR documentation.

    Once KB5089573 (or a later cumulative update) is successfully installed, no further ESP/KIR workaround is required.

    The context does not provide supported steps for:

    • Diagnosing or fixing repeated BitLocker recovery prompts after an update.
    • Restoring the date/time/notification/wifi area after an update rollback.

    Only the ESP‑space‑related update failure and its resolution/workarounds are covered.
