    Hi Muhd,

    It appears that the Datastore folder couldn't be cleared.

    Can you please boot into Safe mode and run that batch file again?

    Instructions to boot into Safe mode are mentioned in this article:

    The Windows Update service seems to be terminating unexpectedly. Please reset the Windows Update cache using this batch file to see if that fixes the issue:

    1. Download the zip file and extract the batch file to the desktop.
    2. Right-click on the batch file, click Properties, click "Unblock" (if present), and OK.
    3. Double-click the batch file to run it.
    4. After it completes execution, don't close it yet.
    5. Right-click on that Command Prompt window, click "Edit" and click "Select all"
    6. Right-click on that Command Prompt window, click "Edit" and click "Copy" (This copies the output to the clipboard.)
    7. Paste the info (Ctrl + V) into your reply window.

    Hi Muhd,

    Error 0x800F0900 ("CBS_E_XML_PARSER_FAILURE") is caused by the corruption of manifests in the component store. If DISM, as suggested by Carl-L, doesn't help, please repair install Windows 11 via Settings.

    Launch Settings > System > Recovery. Under "Fix problems using Windows Update", select Reinstall now.

    This does a repair installation, keeping your files, apps, and settings.

    Hello Muhd Azreen,

    Welcome to Microsoft Q&A forum.

    I see that you are having issue updating Windows. In this case, let try these fixes first.

    • Disable or uninstall any third-party antivirus software.
    • Disable VPN and proxy if applicable.
    • Scan system files for corruption.
      1. Type "Command Prompt" in the search bar and select "Run as administrator".
      2. Type DISM /Online /Cleanup-image /RestoreHealth and press Enter.
      3. Type SFC /scannow and press Enter when the previous scan is done.
      4. Restart your computer.
    • Download and install the KB directly from the Microsoft Update Catalog.
