What NWinfo is

NWinfo is a Windows program for collecting system and hardware information directly, without relying on WMI. It retrieves details about SMBIOS, CPUID, S.M.A.R.T., PCI, EDID, and other hardware. Its command-line interface can export YAML, JSON, LUA, TREE, or HTML, and includes an option to hide MAC addresses and serial numbers. The GUI supports Windows 7 and later, while the CLI supports Windows XP and later. Sensor providers include LibreHardwareMonitor, HWiNFO shared memory, GPU-Z shared memory, and built-in options. GPU information uses NVIDIA NVAPI, AMD ADL2, or Intel IGCL, and requires GPU drivers. NWinfo can run without a driver, though some information may then be unavailable; NVMe support requires Windows 10 or later. The project is licensed under the Unlicense, with source code, releases, nightly builds, and libraries available for download. It also offers a portable version. The maker warns that reading DIMM SPD data may damage hardware, so that capability warrants care.

Good

  • Collects hardware information without relying on WMI.
  • CLI exports YAML, JSON, LUA, TREE, and HTML.
  • CLI supports Windows XP and later.
  • Includes an option to hide MAC addresses and serial numbers.

Watch out

  • Some hardware information may need a driver.
  • NVMe support requires Windows 10 or later.
  • DIMM SPD reads may damage hardware.

Who it suits

NWinfo may suit Windows users who need system and hardware details in a GUI or command-line report. Its export formats and sensitive-data option may help users preparing machine information for review or sharing.

Verdict

NWinfo provides broad hardware inventory and export options across supported Windows versions. Note the driver caveat, NVMe requirement, and warning about DIMM SPD reads before using it.
