Error 0x8007000d when installing Windows 11 Insider Preview Feature Update (26300.9032)

Hi everyone,

I'm currently running into an issue while trying to update to Windows 11 Insider Preview Feature Update (26300.9032). The installation has failed multiple times.

Initially, Windows Update failed with error code 0x8007000D. To troubleshoot, I tried the following:

  • Stopped the Windows Update (wuauserv) and BITS services.
  • Renamed the SoftwareDistribution folder to force Windows Update to download a fresh set of update files.
  • Ran:
    • DISM /Online /Cleanup-Image /CheckHealth
    • DISM /Online /Cleanup-Image /RestoreHealth
    • sfc /scannow
  • Restarted the system after the repairs completed.

DISM /RestoreHealth completed successfully, and sfc /scannow reported that Windows Resource Protection did not find any integrity violations.

Despite these steps, Windows Update continues to fail. To rule out Windows Update itself, I also downloaded the Windows 11 Insider Preview Feature Update (26300.9032) packages from UUP Dump and created an ISO. I then attempted an in-place upgrade by running setup.exe from the generated ISO while keeping my files and apps.

The installation started normally, but after rebooting and completing part of the upgrade process, Windows rolled back to my previous build (26300.8935). Panther logs indicate a migration failure, including error 0x8007042B, after the original Windows Update failures with 0x8007000D.

Has anyone experienced a similar issue or found a workaround? Any advice, troubleshooting steps, or suggestions would be greatly appreciated.😄

Thank you!

    Since DISM and SFC completed successfully and the ISO upgrade also rolled back, this is probably no longer a Windows Update cache problem.

    0x8007000D means that Windows encountered invalid data. 0x8007042B means that an upgrade process stopped unexpectedly, but it does not identify the actual cause. The useful error is normally a few lines earlier in the setup logs.

    Try these steps:

    1. Back up important files and stop repeating the installation for now.
    2. Run Microsoft’s SetupDiag tool as administrator immediately after the rollback. Check SetupDiagResults.log for Matching Profile, Failure Phase, Failure Operation, and any named driver, application or DLL.
    3. Also check these files:

    C:\$WINDOWS.~BT\Sources\Panther\setuperr.log C:\$WINDOWS.~BT\Sources\Rollback\setuperr.log C:\$WINDOWS.~BT\Sources\Rollback\setupact.log

    Start from the bottom and look above the final 0x8007042B entry. If a driver, service or application is named, update or uninstall that specific item before retrying.

    1. Perform a clean boot, temporarily uninstall third-party antivirus, VPN, disk-management and system-tuning software, and disconnect unnecessary USB devices. Update the BIOS, chipset and storage drivers from the PC manufacturer.
    2. Retry through Settings > Windows Update. Avoid using the UUP Dump ISO for troubleshooting because it is not an official Microsoft installation image and can introduce separate package or language-matching problems. Use an official Insider ISO for the same branch only if Microsoft provides one.

    Build 26300 belongs to an experimental Insider branch, so this may also be a flight-specific migration bug. If SetupDiag does not identify a local driver or application, staying on 26300.8935 and waiting for the next flight is safer than repeatedly forcing 26300.9032.
