    My issue is similar except it is 2025-05 Cumulative Update Preview for Windows 11 Version 24H2 for x64-based Systems (KB5058499) which downloads but install fails with error code: 0x800f0991 and your fix did not work for this.

    1.Check Your Internet Connection
    Ensure you have a stable internet connection, as unstable connections can lead to failed updates.
    2. Run Windows Update Troubleshooter
    Go to Settings > System > Troubleshoot > Other troubleshooters.
    Find the Windows Update troubleshooter and run it. It will diagnose and help fix issues.
    3. Clear Windows Update Cache

    Open Command Prompt as an administrator.
    Run the following commands to stop the Windows Update service:



    net stop wuauserv
    net stop cryptSvc
    net stop bits
    net stop msiserver



    Next, rename the SoftwareDistribution and Catroot2 folders:



    ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    ren C:\Windows\System32\catroot2 Catroot2.old



    Finally, restart the services:



    net start wuauserv
    net start cryptSvc
    net start bits
    net start msiserver



    4. Check for Disk Space

    Ensure that your system drive has enough space. Insufficient disk space can cause updates to fail.
