Windows update failures can happen because of corrupted files, windows update service issues or system file errors.
Try these steps:
Restart your computer and run Windows Update Troubleshooter.
Open Command Prompt as Administrator and run:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
Clear Windows Update cache by restarting Windows Update services.
Make sure you have enough free storage space.
If the issue continues, try installing the update using the Windows 11 Installation Assistant.
Also check if your drivers and BIOS are updated, as outdated drivers can sometimes cause update failures.
