I have tried almost everything.

  • Fix problems without resetting your PC.
  • Fix problems using windows update and reinstall it.
  • Reset PC (does not work or completely crashes)
  • Advanced startup
  • Install from scratch and use the windows install directions
  • Command prompts, sft /scannow and the DISM Repair window one (Don't remember exactly it is)
  • Last resort I have even factory reset the computer and still has not fixed it.

And for those thinking it is a hardware problem it was working perfectly until this update was released and now nothing works. Also the sft /scannow comes back without any problems but I still can't update after all of these fixes and some more that I forget that I did.

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

    This issue occurs due to corrupted system files. In this case, kindly follow the steps provided by the AI answer. If the issue persists, I suggest doing an in-place upgrade, wherein it 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 prompt.

    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.

    Note: This is a public forum. I may respond shortly, but I apologize in advance for any delays. I am simply a fellow user trying to provide helpful insights and information.

    Error 0xc0000005 during a Windows 11 25H2 upgrade typically indicates a problem occurring while Windows is trying to install or start components during setup, often after other generic repair steps have already been tried.

    Given that Windows Update repair, DISM, SFC, reset, and even a factory reset have already been attempted, the next practical options are:

    1. Back up data
      • Before further repair or reinstall attempts, back up important files to an external drive or OneDrive as recommended in the general troubleshooting guidance.
    2. Try Windows Update–specific repair steps again in a clean state Even after resets, update components can still be corrupted. Use these steps in this order:
      1. Run the Windows Update troubleshooter
      • Select Start > Settings > Update & Security (or System > Troubleshoot > Other troubleshooters on newer builds).
      • Select Windows Update > Run and follow the prompts.
      1. Reset SoftwareDistribution and Catroot2
      • Open Command Prompt as administrator.
      • Run, one by one:
        • 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 and try the 25H2 update again.
      1. Repair system image and files again in this sequence
      • Open Command Prompt as administrator.
      • Run: DISM.exe /Online /Cleanup-image /Restorehealth
      • When it completes successfully, run: sfc /scannow
      • After SFC reaches 100%, restart and retry the update.
    3. Use Windows Recovery Environment (WinRE) repair options If the system is unstable during the upgrade process, use WinRE:
      • Force WinRE by interrupting boot three times (power on, wait for logo, then hold power to turn off; repeat 3 times) until Automatic Repair appears.
      • Select Advanced options > Troubleshoot.
      • Try in order:
        • Startup Repair (if offered).
        • System Restore (if there is a restore point from before the 25H2 attempts).
        • If still failing, Reset this PC > Keep my files with Local reinstall or Cloud download.
    4. Perform a clean installation of the latest stable Windows 11 (including 25H2) If in-place methods keep failing with 0xc0000005, a clean install is the most reliable way to get to 25H2:
      • Go to the Windows 11 software download page and use the Media Creation Tool to create a bootable USB.
      • Boot from the USB, delete existing Windows partitions if a full wipe is acceptable, and install a fresh copy.
      • If keeping data is required, copy files off to external storage first; a true clean install will remove installed apps and data on the Windows partition.
    5. If on an Insider build
      • If the device is on a 26xxx Insider build, exit Insider by deleting HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost in regedit, restart, then perform an in-place install of the released 25H2 ISO (mount ISO in Windows and run setup.exe).
      • If on a 27xxx Canary build, only a clean install to the public 25H2 build is supported.

    If all of the above fail, the remaining path is a full clean install (delete all partitions during setup) after backing up data externally, as this removes any residual corruption or configuration issues that can cause 0xc0000005 during upgrade.
