Cant find drivers for pci serial port and pci simple communications controller

For missing “PCI Serial Port” and “PCI Simple Communications Controller” drivers in Windows 10 Pro, the devices typically just need the correct vendor driver installed.

Use these steps in order:

1. Identify the devices in Device Manager
   1. Right-click Start > Device Manager.
   2. Look under Other devices (or with yellow warning icons) for PCI Serial Port and PCI Simple Communications Controller.
   3. Right-click each device > Properties > Details tab.
   4. From the Property drop-down, select Hardware Ids and note the VEN_**** and DEV_**** values (these identify the chipset/vendor). Use these IDs on the PC or motherboard manufacturer’s support site to locate the correct driver (often Intel/AMD chipset or Intel Management Engine/AMT driver).
2. Let Windows try to install drivers automatically
   1. Select Start > Settings > Update & Security > Windows Update > Advanced options.
   2. Turn Receive updates for other Microsoft products when you update Windows to On.
   3. Go back to Windows Update and select Check for updates.
   4. If a View optional updates link appears, open it, select all driver updates, then Download and install.
   5. Restart the PC after updates complete.
3. Manually update via Device Manager using downloaded drivers
   1. Download the latest chipset/management engine drivers for the PC or motherboard model from the manufacturer’s official support site (match Windows 10 version and architecture).
   2. Extract/unzip the driver package if needed and note the folder path.
   3. Right-click Start > Device Manager.
   4. Expand Other devices, right-click PCI Serial Port > Update driver.
   5. Choose Browse my computer for drivers.
   6. Browse to the folder where the downloaded drivers are located, select OK, then Next.
   7. Repeat for PCI Simple Communications Controller.
4. If Device Manager still reports no driver
   1. Confirm that the downloaded driver supports Windows 10 and the specific hardware IDs.
   2. If no compatible driver is found, contact the PC or motherboard manufacturer and provide the hardware IDs so they can supply the correct Windows 10 driver or guidance.
