  5. Extract the .cab archive: right-click → Extract All, or run expand -F:* file.cab C:\driver\ in Command Prompt.
  6. Install via Device Manager: right-click your device → Update driver → Browse my computer → point to the extracted folder. Alternatively run pnputil /add-driver C:\driver\*.inf /install.
