Windows 10: Why does Windows Update find drivers for devices that do not exist?

The device name shown below cannot be found in Device Manager, as shown in my post #10.

 

Open up the device in Device Manager and look at the Hardware ID. So if your DRAM Controller in Device Manager has ID VEN_8086&DEV_0C00 then it matches the driver listed in the tool.

 

Unfortunately, there are no DRAM Controller and PCI Express x16 Controller in my Device Manager, as shown in this post.

 

It might have a different name on your system even if Hardware Id matches.

You can use this powershell to get a list of all HWID on your system: Code: Get-WmiObject Win32_PNPEntity | Select Name, DeviceID > "$env:homeDrive$env:homePath\Desktop\Devices.txt"[/quote] Then search for the Device Id in the text file generated on your desktop. This is from my Intel Lenovo. Note that PNP0A03 is shown in WUMT as "AMD PCI bus" but on my system it is called "PCI Bus". It doesn't apply and neither is it selected if you tick the "Selected by Windows update" box.





Similarly if I scan for "VEN_8086" on mine it is called Code: PCI standard host CPU bridge PCI\VEN_8086&DEV_2C62&SUBSYS_219617AA&REV_0...[/quote] You have "PCI standard host CPU bridge" - you could check it and see - it may be same name as mine.

 

Matthew,

[This seems to be a response to a post that has been removed]

Replace the whole of
homeDrive$env:homePath\Desktop\Devices.txt"
with a full path & filename somewhere convenient. I used this, just for example,
Code: Get-WmiObject Win32_PNPEntity | Select Name, DeviceID > "$env:\Desktop\HardwareIDList.txt"[/quote] Denis

 

Thanks to all of you. I got the following:
---------------------------------------------------------------------------------------
Intel (R) Xeon(R) processor E3 - 1200 v3/4th Gen Core processor DRAM Controller.
Hardware ID: PCI\VEN_8086&DEV_0C00

PCI standard host CPU bridge
DeviceID: PCI\VEN_8086&DEV_0C00&SUBSYS_85341043&REV_06\3&1158365...
---------------------------------------------------------------------------------------
Intel (R) Xeon(R) processor E3 - 1200 v3/4th Gen Core processor PCI Express x16 Controller.
Hardware ID: PCI\VEN_8086&DEV_0C01

PCI-to-PCI Bridge
DeviceID: PCI\VEN_8086&DEV_0C01&SUBSYS_85341043&REV_06\3&1158365...
---------------------------------------------------------------------------------------
Both "PCI standard host CPU bridge" and "PCI-to-PCI Bridge" are shown in my Device Manager, but I wonder why they are called "DRAM Contoller" and "PCI Express x16 Controller" respectively in WUMT.

I removed it because the code had actually worked. I just didn't notice Devices.txt on my desktop.

 

"PCI standard host CPU bridge" and "PCI-to-PCI Bridge" are the generic devices names that are built-in to Windows (in machine.inf and pci.inf, respectively).

When you install the Intel "driver" INF update it assigns the Intel-branded name.

Note that this is purely cosmetic - the drivers associated with these two devices are already built-in to Windows and don't get updated.

 

Do you mean the names will be changed when I have installed the software in this thread?

 

Correct.

 

Is it correct to say the following?

Although my PC has no Xeon processor, the controllers below do exist on my Pentium G3240, a 4th Gen processor.

1. Intel (R) Xeon(R) processor E3 - 1200 v3/4th Gen Core processor DRAM Controller.
2. Intel (R) Xeon(R) processor E3 - 1200 v3/4th Gen Core processor PCI Express x16 Controller.

 

Yes, my Core i7 also says "Xeon." This is just a side effect of all the Intel processors in the same family using the same device IDs for the host bridge.
