PCI-Z is a hardware device information viewing and detection tool similar to CPU-Z and GPU-Z. They are both very simple and compact free tools for Windows. The difference is that it is used to view detailed information of various PCI devices, including detecting information about various unknown PCI/PCI-E/PCI-X devices installed on a computer, even if your Device Manager cannot identify them.

Its primary purpose is to detect unknown hardware on Windows-based PCs and assist users in identifying the vendor, device, and other relevant details about the device, even in the absence of installed drivers. It leverages the The PCI ID Repository, a publicly accessible repository containing all known IDs associated with PCI devices, including vendors, devices, subsystems, and device classes.

By utilizing this repository, PCI-Z enables the display of user-friendly, human-readable names instead of obscure numeric codes, similar to the functionality offered by the lspci Linux command. Notably, PCI-Z offers full support for Windows operating systems, making it a reliable resource for locating drivers for various PCI peripherals such as Wi-Fi cards, audio cards, network cards, and more.

PCI-Z can run on Windows XP and higher, Windows Server 2003 and higher, and Windows PE. For older operating systems (such as Windows 2000, Windows Server 2000, BartPE, Reatogo, ReactOS), you can use the legacy version (v1.31).
