[Share] Windows Configuration and Security Inspection Tool (with CSV Export Feature)

A configuration and security inspection tool written in Go

Author: Pecezen.org
Platform: Windows
Language: Go

When preparing for ISO/IEC 27001 certification, under control 8.9 Configuration Management, auditors commonly review the following aspects.

The operating system versions of servers and personal computers.
Whether any unauthorized software has been installed.
Whether firewall and antivirus software are properly enabled.
Whether any unnecessary system services are running.

So I decided to write a simple configuration and security inspection tool. I recently had some free time, so I’m sharing it here for everyone’s reference.

✅ Tool Features Overview：

🖥️ Hardware Information
🧩 Operating System (OS) Information
📦 Installed Software List
🛡️ Antivirus Status
🔥 Firewall Status
⚙️ System Services Status
📤 Supports CSV Export for auditing or record-keeping
🌐 Multi-language Interface (Traditional Chinese / English / Japanese / German)

🖥️ User Interface：

💾 Download the Windows Version

You can use the source code below to compile the program yourself, but we’ve also included a ready-to-run Windows executable for your convenience.：
