Windows 10 does not know some "devices" of a Dell Precision Workstation

I was installing Windows 10 on a Dell Precision T3620 Workstation. Although the systems worked well, it bothers me that the Windows Device Manager reported that some devices were not recognized, i.e., an yellow exclamation point on the devices, like the following screenshot shows,

In fact, these unrecognized devices are,

• PCI Data Acquisition and Signal Processing Controller,
• PCI Memory Controller, and
• SM Bus Controller

It turns out that many users had similar problem, and the solution is to update some device drivers. However, I was slightly frustrated that the very driver that solved my problem (all three unrecognized devices) wasn't listed under "driver" on the Dell Support's website. Instead, it was listed under "Utility", and was the "Intel Chipset Device Software."
