Hello,
To install a CAB file in Windows 10, please refer these steps:
- Open administrative Command Prompt.
- Type following command after substituting correct CAB file path and press Enter key:
dism /online /add-package /packagepath:"<PUT-CAB-FILE-PATH-HERE>"
- This should let you install the update.
If this doesn't works, re-check Windows Update Catalog website, and make sure you downloaded the correct update file. In case if the update is from third-party vendor, please try to get their support on the issue.
You can additionally run Windows Update troubleshooter to fix issues with Windows Update:
