You might think, "It’s 2023; Windows 10 has millions of drivers built-in." That is true for common peripherals, but chipset drivers are proprietary.
Dell modifies reference designs from Intel, AMD, or NVIDIA. The SM Bus Controller on a Dell Latitude 5490 uses a different hardware ID than the one on a Dell XPS 8930. Windows 10’s generic driver does not recognize Dell’s specific PCI vendor IDs (VEN_8086, VEN_1022, etc.) combined with Dell’s subsystem IDs (SUBSYS_1028...).
Thus, you must download the driver directly from Dell or use a tool designed to extract Dell’s proprietary chipset package. Open Settings > Update & Security > Windows Update

Do not trust third-party "driver updater" tools; always download directly from Dell or Intel to ensure your system stays safe.
