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 from the same directory in the following order: PawnIO -> HwRwDrv -> WinRing0.

Driver	Author	License	Notes
PawnIO	namazso	GPL v2	Safe to use, but some hardware information may be unavailable.
HwRwDrv	Faintsnow	Closed source	May be flagged as a virus by antivirus software and detected by anti-cheat systems.
WinRing0	hiyohiyo	BSD	Listed as a vulnerable driver by Microsoft, detected as a virus, and triggers anti-cheat software.

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