Howto solve error code 0x80240473

To resolve error code 0x80240473, follow these detailed steps:

  1. Check your internet connection: Ensure that you have a stable internet connection. Try accessing another website or service online to confirm connectivity.
  2. Restart the Windows Update components: Open Command Prompt as an Administrator and execute the following commands in sequence:
    – `net stop wuauserv`
    – `net stop bits`
    – `net stop cryptsvc`
    – Navigate to C:\Windows\SoftwareDistribution and rename the folder to something else, such as “SDold”. Then, repeat for C:\Windows\System32\catroot2 (renaming it to “CATold”). Restart the services using:
    – `net start wuauserv`
    – `net start bits`
    – `net start cryptsvc`
  3. Reset Windows Update: In Command Prompt as Administrator, type and run these commands sequentially:
    – `wuauclt /resetauthority /detectnow`
    This will reset the Windows Update component to its default state and then initiate a new update check.
  4. Run System File Checker (SFC): Open Command Prompt as an Administrator again. Execute:
    – `sfc /scannow`
    This command scans all protected system files and replaces incorrect versions with correct Microsoft copies, fixing potential corruption issues.
  5. Enable Windows Update from Group Policy Editor (for Pro/Enterprise editions): Launch gpedit.msc via Run dialog or similar. Navigate to Local Computer Policy > Administrative Templates > Windows Components > Windows Update. Double-click “Specify Intranet Microsoft update service location” and set it to “Disabled”. Do the same for “Configure Automatic Updates”, setting it to “Notify download and notify for install”.
  6. Run DISM Tool: Execute the following commands in Command Prompt as Administrator:
    – `DISM /Online /Cleanup-Image /StartComponentStore`
    – `DISM /Online /Cleanup-Image /ScanHealth`
    – `DISM /Online /Cleanup-Image /RestoreHealth`
    These commands will clean up the component store, scan for and repair any problems with system files.

If none of these methods resolves 0x80240473 error, further investigation may be required, such as examining Event Viewer logs or seeking assistance from Microsoft Support for more advanced diagnostics.
