    Hi!

    Are you upgrading from Windows 10 to Windows 11 25H2, from another edition of Windows 11 (23H2, 24H2) to 25H2, or are you installing cumulative updates for 25H2?

    Have you tried uninstalling Vanguard and then attempting to install the updates? That is a recommendation. Anti-cheat software, VPNs, third-party antivirus programs, and internet banking software can cause this behavior.

    For 0x8007001f on Windows 11 25H2, use this order of troubleshooting:

    1. Run the built-in Windows Update troubleshooter.
      • Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
      • Find Windows Update and select Run.
    2. Check free disk space.
      • Windows needs at least 16 GB free for a 32-bit OS or 20 GB for a 64-bit OS to upgrade.
      • If storage is low, free space first.
    3. Restart the PC, then try the update again.
      • A restart can clear apps or services blocking the install.
    4. Disconnect nonessential hardware.
      • Remove USB drives, external hard drives, printers, scanners, speakers, headphones, and undock the laptop if it is docked.
    5. Temporarily uninstall third-party antivirus or security software.
      • This can interfere with Windows upgrades and updates.
      • Make sure installation media or product keys are available before uninstalling.
    6. Repair the Windows image and system files.
      • Open Command Prompt as administrator.
      • Run: 
             DISM.exe /Online /Cleanup-image /Restorehealth
      • Wait for the success message.
      • Then run: 
             sfc /scannow
      • Wait until verification reaches 100%, then try Windows Update again.
    7. Reset Windows Update components.
      • This is an advanced step and requires administrator permissions.
      • Open Command Prompt as administrator and run these commands one at a time: 
             net stop bits
     net stop wuauserv
     ren %systemroot%\softwaredistribution softwaredistribution.bak
     ren %systemroot%\system32\catroot2 catroot2.bak
     net start bits
     net start wuauserv
      • Restart the PC after the commands finish.
    8. Check the drive for file system errors.
      • In Command Prompt as administrator, run: 
             chkdsk /f C:
      • Restart when prompted.
    9. Try a clean restart of Windows.
      • A clean restart starts Windows with minimal drivers and startup programs, which can help if another app is blocking the update.
    10. If the issue still continues, use the Get Help Windows Update troubleshooter first, then consider a clean installation of Windows 11.
      • Back up personal files before major repair steps.

    About the Riot/Vanguard issue: the current Windows 11 25H2 known issue in the context is a separate investigation affecting a limited number of games after KB5121003, with symptoms such as games becoming unresponsive, closing unexpectedly, EXCEPTION_ACCESS_VIOLATION, or device restarts. The listed affected games are ARC Raiders, MARVEL Tōkon: Fighting Souls, and The Finals. That does not identify Riot Vanguard as the cause of 0x8007001f.
