You can update all drivers at once in Windows 10 using a driver update program. Though most of them are not complete, most of them fulfill you needs. In addition, Windows 10 automatically provides updates to your drivers using Windows Update. If that doesn't work out then you can either go out the manual method or find from the manufacturer page. Here is a very simple way to manually update each driver. Open Device Manager and right-click on the device. Update Driver > Choose Update Driver Software from the left menu.
