I only get drivers from their official sources. I'll never trust a driver updater. While they may work sometimes, other times they may download a generic driver that doesn't work well with your specific hardware, especially on laptops (ie. a driver updater downloading an updated Realtek Audio driver on an MSI laptop I had then the MSI sound utility called Nahimic for enhancing audio stops working because the driver is not supported). To each their own offcourse but I like only getting them from official sources.
For LAN/WLAN/Bluetooth, I get them either from
Intel's site or from
Realtek depending on the device I am updating. For video drivers, from
nVIDIA and/or
Intel or
AMD directly
