Hello, thank you for reaching out to Microsoft Q&A.

Error 0x80070476 occurs due to corrupted update files or Windows update components. You can first try these basic troubleshooting steps and see if it helps.

Option 1. Try running the Windows update troubleshooter.

Go to Start > Settings > System > Troubleshooter > Other troubleshooter > Windows update

Option 2. Run the System File Checker utility scan.

Open the Command Prompt as an Administrator window.
Execute these commands one by one and press Enter after each command.

Dism /Online /Cleanup-Image /ScanHealth

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /RestoreHealth

sfc /scannow

Option 3. Reset Windows Update components

Open the Windows PowerShell as an Administrator window.
Execute these commands one by one and press Enter after each command.

net stop wuauserv
net stop cryptSvc
net stop bits
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
netsh winsock reset

Once completed, restart your computer and install the updates. Let me know how it goes.

I have the same issue but the above steps did not solve it.

FWIW to anyone else, Option 1 did not solve the issue for me. Option 2 said it found corrupt files and repaired them but ultimately didn't fix it either (the install reaches 100% but then still errored out). Option 3 actually worked for me.EDIT: I take it back. Option 3 didn't work for me either. It said it was Complete and gave no indication of an error. But when I clicked Check for Updates, it then came back and said Windows 11 version 25H2 is available and that the last attempt failed. And again it's back to failing after reaching 100%.

option 1 did not work for me, open 2 and 3 ran to the end without errors but did not solve the issue. What worked for me is this: https://free.blessedness.top/nl-nl/answers/questions/5593436/windows-update-25h2-geeft-foutmelding-0x80070476 (manual install of 25H2)

However I have now the same issue with the next (security) update...
