Failed to upgrade older Windows 10 systems

A laptop running an older version of Windows 10 encountered an upgrade failure while attempting to update to a newer version. The process ultimately failed and displayed an error message for which solutions are difficult to find through standard searches. Assistance is requested for pinpointing the specific issue and identifying a resolution method.

    Download the Windows 10 Media Creation Tool from Microsoft.

    Create a bootable USB or ISO.

    Run the setup directly from media to perform the upgrade.

    This can bypass some Windows Update issues.

    Note the exact error message or code displayed during the upgrade failure.

    If no specific code is shown, check Windows Update logs:

    Open Event Viewer (Win + R, type eventvwr.msc, press Enter).

    Navigate to Windows Logs > Application and System.

    Look for recent errors or warnings related to Windows Update or setup failures.
