Hello Alan Chen3,
this error usually means that your system is missing some necessary files that prevent the update from being completed.
You can try to resolve it by specifying the source location:
- Open the Command Prompt (administrator privileges).
- Enter the following command and press Enter: DISM.exe /Online /Cleanup-image /Restorehealth /Source:C:RepairSourceWindows /LimitAccess
Note that replace "C:RepairSourceWindows" with the path of your Windows installation media. For more details, you can see Configure a Windows Repair Source | Microsoft Learn.
- Wait for the command to complete, which may take some time.
Hope it helps.
Kind regards,
Lei
