PCI Simple Communications driver
On most Intel PCs, PCI Simple Communications Controller is the Intel Management Engine Interface (HECI). Install the Management Engine driver from your PC maker, or from Intel's Management Engine Drivers for Windows 10 and 11 page on supported processors. Check the hardware ID first.

The short version
What to install and where it comes from. Every link goes to the manufacturer or Microsoft, never to a copy.
Official files only, nothing bundled
Step by step
Check the hardware ID
Open the entry in Device Manager, then Properties, Details, Hardware Ids. A line with VEN_8086 and a name like HECI in our table points to the Intel Management Engine.
Let Windows Update try
Go to Settings, Windows Update, Advanced options, Optional updates. Management Engine Interface drivers are often offered there for supported machines.
Download from the PC maker
Search your model on Dell, HP, Lenovo, ASUS or the board maker's site. Look under Chipset or System for Intel Management Engine Interface or Intel ME.
Use Intel's page for newer processors
If the maker has nothing, open Intel's Management Engine Drivers page, check that your processor generation is in its list, and read the included installation guide.
Restart and rescan
After the installer finishes, restart, then use Action, Scan for hardware changes in Device Manager.
Confirm the new name
The entry should move to System devices as Intel Management Engine Interface. If it does not, re-check the ID against the package.
Why Windows uses this vague name
Windows names unknown parts by their class code, not by their maker. A chip that announces itself as a simple communications device and has no matching INF file shows up as PCI Simple Communications Controller. On Intel PCs, the most common chip behind that name is the Management Engine Interface, called HECI in the public PCI ID list. The entries in the table show how the list labels it for several chipset generations.
What the driver gives you
The Management Engine is a separate small processor in the chipset. It helps start the PC, handles parts of power management and security, and supports remote management on business machines. The Windows driver is the doorway between that processor and the operating system. Without it, the entry stays flagged, and firmware update tools from the PC maker may fail to detect the engine.
Which source to trust
Intel states that its Management Engine page covers Intel Core processors from the 7th generation up to the 14th generation and the Core Ultra families. The page also carries a license line aimed at evaluation use, so for a retail laptop or desktop your maker’s package is the cleaner choice. Makers fit the engine firmware to their own board, and their driver is matched to it.
If the ID is not Intel, do not install this package. Search the vendor code in the PCI ID Repository instead, or note that some modem and serial add-in cards use the same class name.
Questions
Is the Management Engine a virus or spyware?
No. It is a small processor built into Intel chipsets that handles start-up tasks, power features and, on business PCs, remote management. The driver only lets Windows talk to it.
Do I need this driver to use the PC?
Windows runs without it. Some power, security and firmware update features rely on it, so install it to stay supported.
My PC has an AMD processor.
The Intel Management Engine does not exist on AMD systems. An unknown communications entry on an AMD machine needs its hardware ID checked, and the fix is usually the AMD chipset driver or the PC maker's package.
Why is Intel's package so large?
Intel's page lists a 1.2 GB download that bundles many versions for different generations and an installation guide. Your PC maker's single installer is usually much smaller.
