NWinfo review
A broad Windows hardware inspector with GUI, CLI, scripting, and structured exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NWinfo is an open-source Windows Win32 utility for collecting detailed system and hardware information. It is aimed at administrators, technicians, developers, and technically minded users who need low-level visibility into a Windows machine. The product covers SMBIOS, CPUID, S.M.A.R.T., PCI, SPD, EDID, UEFI, disks, networks, displays, GPU sensors, and other hardware components. It provides both a graphical interface and a command-line interface, with a PowerShell hardware and system reporting script for repeatable reporting tasks.
Its strongest area is collection depth. NWinfo can inspect UEFI information and variables alongside firmware, memory, storage, display, network, and GPU details, giving it a wider hardware focus than a basic system summary tool. Output can be produced in JSON, YAML, HTML, LUA, or TREE formats, which supports both human-readable reports and structured processing. The combination of GUI, CLI, scripting, and a portable version also makes it suitable for different diagnostic and documentation workflows.
NWinfo’s pricing model is straightforward: it is free and open-source. The published platform details show GUI support for Windows 7 and later, while the CLI supports Windows XP and later. That makes the command-line component useful for older Windows environments, although the separate version ranges add a compatibility point to check before standardizing deployments. NWinfo is a strong choice when hardware, firmware, and sensor visibility matter most. Organizations seeking detailed software inventory or support for operating systems beyond Windows should choose a different system information product.
