NWinfo

NWinfo is a Win32 program that allows you to obtain system and hardware information.

Features

• Obtain detailed information about SMBIOS, CPUID, S.M.A.R.T., PCI, EDID, and more.
• Support exporting in JSON, YAML, and HTML formats.
• Gathers information directly without relying on WMI.

Download

The source code is maintained in a git repository at https://github.com/a1ive/nwinfo.
You can download the latest version of the binary from GitHub Releases.

CLI (nwinfo)

Usage

.\nwinfo.exe OPTIONS

Example Commands

.\nwinfo.exe --format=json --output=report.json --cp=UTF8 --sys --disk

Exports system and disk information to report.json in JSON format.

.\nwinfo.exe --pci=03

Prints information about all PCI devices in the class code 03 (Display Controllers).

PowerShell Script for System Diagnostics

hw_report.ps1 is a PowerShell script designed to generate and display a detailed hardware and system report using nwinfo.

Notes

Windows XP

This project is compatible with Windows XP using YY-Thunks, but it may not retrieve some hardware information.

Supported Drivers

This project searches for and loads drivers in the following order: CPUZ161 -> EVGA -> HwRwDrv -> WinRing0 -> PawnIO.

Driver	Filename	License	Notes
PawnIO	PawnIO.sys	GPL v2	Safe to use, but some hardware information may be unavailable.
HwRwDrv	HwRwDrvx64.sys	Closed source	May be flagged as a virus by antivirus software and detected by anti-cheat systems.
WinRing0	WinRing0x64.sys	BSD	Listed as a vulnerable driver by Microsoft, detected as a virus, and triggers anti-cheat software, not provided in the releases.
CPUZ161	cpuidx64.sys	Closed source	Safe to use, not provided in the releases.
EVGA	HwIox64.sys	Closed source	May be flagged as a virus by antivirus software and detected by anti-cheat systems, not provided in the releases.

Note: The program can still run normally even if all drivers are removed, but some hardware information may not be accessible.

PawnIO Driver Installation

Install the PawnIO driver silently using the following command:

.\PawnIOSetup.exe -install -silent

Uninstall the PawnIO driver silently using the following command:

.\PawnIOSetup.exe -uninstall -silent
