    Hi, I'm Bernard. I'm happy to help!

    The error code 0x80070003 means that the update is unable to install correctly due to a misconfiguration. To sort out the issue, kindly follow the steps below:

    Reset Windows Update components:

    Open Terminal (Admin) or Windows PowerShell(Admin) (Press Windows key + X then click Terminal(Admin))

    Copy, paste, and enter the command below:

    net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"
rmdir %systemroot%\SoftwareDistribution /S /Q
rmdir %systemroot%\system32\catroot2 /S /Q
regsvr32.exe /s atl.dll
regsvr32.exe /s urlmon.dll
regsvr32.exe /s mshtml.dll
netsh winsock reset
netsh winsock reset proxy
net start bits
net start wuauserv
net start appidsvc
net start cryptsvc

    Once done, restart the device and check.

    If none of the above solutions work, I suggest doing an in-place upgrade, which will upgrade the device to the latest version and repair all issues without deleting any files.

    Go to the Windows 11 website: https://www.microsoft.com/en-us/software-download/windows11

     

    Under Download Windows 11 Disk Image (ISO), select Windows 11 (multi-edition ISO)

     

    1.     Once done downloading the ISO, kindly right-click on the ISO, then click Mount>click Setup.exe

    2.     You may be prompted by User Account Control. Click on Yes if so

    3.     In the Install Windows 11 dialog, click Next

    4.     Setup will check your PC and show a license agreement. Click on Accept in the license terms dialog.

    5.     Wait for the setup program to check for the available free space.

    6.     On the Ready to install page, make sure Keep personal files and apps has been checked.

    7.     Then click Install and just follow the prompts.

    8.     Windows 11 will restart your device several times and lead you to the lock screen. Depending on the options you set, it will keep all your files, apps, and user accounts.

    Error 0x80070003 means the update failed to install. Microsoft also notes this error can indicate missing or inaccessible files.

    Since the update has already failed many times, use this order:

    1. Run the Windows Update troubleshooter
      • Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
      • Run Windows Update.
      • Apply any fixes it finds, then restart and try the update again.
    2. Reset the Windows Update cache
      • Press Win + R, type services.msc, and press Enter.
      • Find Windows Update, right-click it, and select Stop.
      • Open C:\Windows\SoftwareDistribution.
      • Delete the files and folders inside it.
      • Go back to Services, right-click Windows Update, and select Start.
      • Try Windows Update again.
    3. Use the repair reinstall option in Settings
      • Go to Settings > System > Recovery.
      • Under Fix problems using Windows Update, select Reinstall now.
      • This performs a repair installation while keeping files, apps, and settings.
    4. If 25H2 still will not install, do an in-place upgrade using Windows 11 installation media
      • The most successful method reported for failed 25H2 upgrades is using the Windows 11 ISO / Media Creation Tool.
      • Before starting:
        • Make sure the ISO language matches the current Windows display language.
        • Disconnect from the internet.
        • Disconnect external devices except mouse and keyboard.
        • Temporarily disable third-party antivirus.
      • Mount the ISO in File Explorer, run Setup.exe, and choose the option to keep files and apps.
    5. If the in-place upgrade also fails
      • Contact Microsoft Support.
