Version 2.21

🧰 Portable Sysinternals System Tester v2.21

Thumb-drive friendly, no-install Windows hardware health check toolkit powered by Sysinternals and PowerShell.

A zero-dependency PowerShell solution that runs a comprehensive, curated set of Sysinternals and Windows diagnostic tools. It then processes the raw data to produce two essential reports: a Clean Summary Report (human-readable, de-noised, with recommendations) and a Detailed Report (cleaned tool outputs).

The essential utility for:

• Field diagnostics and client handoff reports.
• Establishing a system baseline health check.
• Quickly identifying performance bottlenecks.

🚀 Quick Start

Option A: Batch Launcher (Recommended)

1. Download or clone this repository
2. Run SystemTester.bat (will request admin elevation)
3. Choose Option 5 to auto-download Sysinternals Suite (first time only)
4. Choose Option 6 to set up GPU testing tools (optional)
5. Choose Option 1 for interactive menu or Option 2 to run all tests
6. Reports are saved in the script directory

Option B: Direct PowerShell

# Interactive menu
powershell -ExecutionPolicy Bypass -File .\SystemTester.ps1

# Run all tests automatically
powershell -ExecutionPolicy Bypass -File .\SystemTester.ps1 -AutoRun

ℹ️ Launcher compatibility: The batch launcher automatically detects either SystemTester_FIXED.ps1 or the legacy SystemTester.ps1 filename, so both naming conventions continue to work.

First-Time Setup

If Sysinternals tools are missing:

1. Automatic: Use launcher Menu Option 5 to download (~35 MB)
2. Manual: Download from live.sysinternals.com, extract to .\Sysinternals\

For enhanced GPU testing:

1. NVIDIA GPUs: Install latest NVIDIA drivers (includes nvidia-smi)
2. AMD GPUs: Install latest AMD drivers
3. GPU-Z (Optional): Use launcher Menu Option 6 → 1 to download

Full Changelog: v2.1...v2.2

Version 2.1

Release v2.1: Tool Integrity Verification and Enhanced Stability

We are excited to announce version 2.1 of the Portable Sysinternals System Tester! This release focuses heavily on security, integrity, and stability, ensuring the tools you download and run are exactly what they should be, and that the script runs reliably across different environments.

🚀 Key Highlights in v2.1

The biggest addition in this release is the focus on tool validation.

• ✅ Tool Integrity Verification: All Sysinternals executables are now checked for valid digital signatures upon execution or when using the new launcher option. This confirms the tools have not been tampered with and come directly from Microsoft.

• 📏 File Size Validation: The script can now detect and report corrupted or incomplete Sysinternals Suite downloads, preventing silent failures.

• 🔧 Launcher Menu Updates: The menu has been updated to reflect the new functionality:

  • Option 4: Verify Tool Integrity (Signatures)

  • Option 5: Download/Update Sysinternals Suite

📦 Installation / Upgrade Instructions

If you are upgrading from a previous version, simply replace your existing SystemTester.ps1 and SystemTester_Launcher.bat files.

Quick Start (Recommended)

1. Download or clone the new repository files.

2. Run SystemTester_Launcher.bat (requests admin elevation).

3. Choose Option 5 to download or update the Sysinternals Suite.

4. (Optional) Choose Option 4 to verify the digital signatures of all your tools.

5. Choose Option 1 or Option 2 to run the diagnostics.

⚙️ Architecture and Fixes

A number of under-the-hood improvements were implemented to enhance reliability:

• Consistent Path Resolution: Fixed issues related to $PSScriptRoot handling, ensuring the script can consistently find the .\Sysinternals folder regardless of how it is executed (dot-sourced or direct execution).

• Corrected Tool Extension Handling: Resolved issues in verification routines that sometimes incorrectly handled tool extensions.

• Enhanced Error Messages: Improved debugging output and provided more helpful guidance when tools are missing or corrupted, simplifying troubleshooting.

🗺️ Sneak Peek at v2.2

We're already working on the next release! Planned features for v2.2 include:

• HTML report export with charts and graphs.

• Baseline comparison mode (compare current vs. previous tests).

• Skip flags (-SkipCPU, -SkipNetwork, etc.) for test customization.
