Hello,
              So, I've been having an issue with my PCI drivers, and it has been bothering me a ton. 3 devices show up: PCI Device, PCI Simple Communications Controller and Unknown Device. All of which have no drivers. Please provide me with drivers. 

Device: HP ProBook 450 G1
OS: Windows 11 Pro

Hi:

 

You need these drivers:

 

PCI Device:

 

Realtek PCIe Media Card Reader Driver

 

sp84713.exe

 

 PCI Simple Communications Controller:

 

Intel Management Engine Components Driver

 

sp74763.exe

 

Unknown device:  Probably this one:

 

HP 3D DriveGuard Software

 

sp71708.exe

 

If sp71708 does not install the Unknown Device, please post the hardware ID for it so I can figure out what driver it needs.

 

Use this guide for how to find the hardware ID for a device:
