KB5063523 fails install regardless of number of reboots or Safe boot.

O/S: Win10 Pro 22H2 x64

WinRE version: 10.0.26100.1710

Tried:

  • Run WUpdate Troubleshooter - fails to launch due to error 0x80070003
  • Reboot & Update - install fails
  • Clean boot & Update - install fails
  • Safe Mode DISM and SFC regimen - no issues found. Reboot and Update - install fails.

This KB is supposed to remedy a WinRE issue associated with April update KB5057589 which installed successfully on this machine.

WinRE partition is 829MB and has >250MB free.

C:\WINDOWS\system32>fsutil volume diskfree \?\GLOBALROOT\device\harddisk0\partition4

Total free bytes : 316,579,840 (301.9 MB)

Total bytes : 869,265,408 (829.0 MB)

Total quota free bytes : 316,579,840 (301.9 MB)

So, something is definitely borked and it may be due to having recently swapped out the mobo.

Suggestions...?

Thx

    Hi Tocguy,

    I'm Cherrelyn, I'm here to help and I know how frustrating it is when an update like KB5063523 fails after multiple attempts. Since you’ve already done DISM, SFC, Safe Boot, and confirmed that the WinRE partition has enough space, the issue may be related to the motherboard swap or an underlying update misconfiguration.

    Please try these suggestion:

    1. Manually reset Windows Update components**:** Open Command Prompt as admin and run these commands one by one:

    net stop wuauserv

    net stop cryptSvc

    net stop bits

    net stop msiserver

    ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

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

    net start wuauserv

    net start cryptSvc

    net start bits

    net start msiserver

    Then restart your PC and try the update again.

    2. Rebuild WinRE manually: If the update still fails, WinRE might be misaligned after the hardware change. You can temporarily disable and re-enable it:

    reagentc /disable

    reagentc /enable

    This often realigns the configuration and allows the patch to apply.

    Let me know about my suggestion, I'm here to guide you for further assistance.

    Warm regards,

    Cherrelyn

    All this was in preparation for my Wile E. Coyote moment of jumping off the cliff, i.e., the In-Place upgrade to Win 11.

    Aaaaa aaaa aaa aa a ==|-

    Oh, caught a branch. Huh, it went ... OK! I'm a little freaked out about that but in a good way.

    Another of life's little mysteries; this KB now does not appear as a WUpdate nor does it appear in History.
