Windows 10: PCI Serial Port not installed Code 28

I have a refurbished HP Compaq 6000 Pro SFF 32-bit desktop.
The original OS was Windows 7 Pro, I upgraded to Windows 10 Pro in Feb 2016.
In June I upgraded the original ST3160318AS 160GB HDD with a Crucial MX200 250GB SSD
On Wed July 20, did a clean install per
https://www.tenforums.com/tutorials/1...n-install.html
and that went well.
NOTE: The only reason I did the clean install is because I wanted to see how to do that.

However now there is an issue with the PCI Serial Port in Device Manager which wasn’t there before the clean install. I would like to know
--- What is the PCI Serial Port for?
--- Is there a PCI Serial Port driver for my system?





Following is the information about it on my computer.

PCI Serial Port. The drivers for this device are not installed. (Code 28)

Hi Kristen,

Sorry for the inconvenience caused.

Graphics device driver error code 28

The driver for this device isn’t installed. Here’s how to install it:

• Open Start, enter (or type) Device Manager, then select
  Device Manager from the list of results.
• Find your broken device in the list (it will often have a yellow exclamation point next to it).
  
• Right-click (or press and hold) the name of the device, then select Properties > Driver tab > Update Driver.

If you’re asked for the driver and don’t have it, you can usually go to the manufacturer’s website and download the latest driver for your device.

You may visit the HP drivers site and download the drivers by putting in the make/model of your PC. Link is given below.

No idea what a "PCI Serial Port" is. (Serial port off the PCI bus?)

I'm not sure that you need to do anything about it, but see here:

http://h30434.www3.hp.com/t5/Noteboo...o/td-p/4977584

Intel driver support for the Q43 chipset used in that PC seems to end with Windows 7. Perhaps drivers for that OS will work in 10, as they did in 8.1.

 

Edit: Already covered

To add the Win7 driver should work or disable it in device manager and forget it.

I'm guessing its the Com port relating to the dialup modem.

 

This is the driver: http://h20565.www2.hp.com/hpsc/swd/p...&swEnvOid=4059
And I doubt you do anything that requires it so I really don't think it matters... But if the imperfect device manager bugs you go ahead and install it Win7 drivers worked fine on win10 with my old Intel P55 board/1st gen i7

 

I think I'll leave it alone for now. I've researched what PCI Serial Port is for.
I'd say it could relate to the PS/2 ports as well as another one similar to the VGA port, none of which I use.
Serial port - Wikipedia
Maybe the dial up Com port as mentioned but I can't tell if I have one.
I tried that driver link but I got a dialog box that reads "The publisher has been blocked from running software on your machine"
Whatever is going on I'm not sure yet especially since HP does run software on my machine.
Anyway unless a problem occurs that looks like it's related with the PCI Serial Port, I'll wait until then.

 

Have an old Dell Optiplex model that I upgraded to Windows 10, and I got the same thing.

The only component not accounted for in Device Manager was some specialized remote mangement device for which driver support had been discontinued. It was also flagged as a "PCI serial port".

Ignored it, and the machine continues to run fine.
