Installation Error 0x800f081f While Updating to Windows 11

[UIUser]

I'm attempting to install the Windows 11 update (2024-07 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems, KB5040442), but it fails with installation error 0x800f081f.

How can I resolve this without losing any data or program files?

Try running the Windows Update Troubleshooter first. Go to Settings > System > Troubleshoot > Other troubleshooters and select "Windows Update." It might fix the issue automatically.

You could also try resetting Windows Update components manually. Open Command Prompt as an administrator 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, try the update again.
