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.
Version 2.21 introduces comprehensive GPU testing capabilities, advanced network speed/latency testing, and fixes several critical bugs that prevented the script from running properly.
- 🖱️ One-click Menu or Autorun — interactive menu or
-AutoRunparameter - 🧹 Output Cleaner — removes banners, EULA text, usage blocks for readable reports
- 🧠 Comprehensive Tests — CPU, RAM, Disk, GPU, Network, OS Health, Windows Update status

Solution: Use launcher Menu Option 5 to auto-download, or manually download from live.sysinternals.com
Solution: Use launcher Menu Option 3, or run: Set-ExecutionPolicy RemoteSigned -Scope CurrentUser -Force
Solution: Right-click launcher and choose "Run as administrator"
Solution: ✅ FIXED - Use SystemTester.ps1 instead. Original had missing Initialize-Environment function.
Solution: ✅ FIXED - Use SystemTester.bat and SystemTester.ps1. Missing function has been added.
Solution: ✅ FIXED - Script now checks ALL registry subkeys (\0000, \0001, \0002, etc.), not just \0000.
Solution: ✅ FIXED - Launcher now validates file size (should be >1MB). Re-download if size is too small.
Solution: ✅ FIXED - Incorrect code has been removed from SMART test function.
Solution: Ensure Windows Update service is running; may require administrator rights
Solution:
- For NVIDIA: Install latest drivers from nvidia.com
- For AMD: Install latest drivers from amd.com/support
- nvidia-smi is included with NVIDIA drivers
- Some GPU tests don't require special tools and should always work
- Note: AMD detection now properly checks all registry locations
Expected: Some tests are intentionally slow:
- CPU Performance: 10-30 seconds
- Power/Energy Report: 15-20 seconds (admin only)
- Windows Update Search: 30-90 seconds
- DISM/SFC Scans: 5-15 minutes each (admin only)
- DirectX Diagnostics (dxdiag): Up to 50 seconds
- Admin Rights: Required for DISM, SFC, energy reports, SMART data, Windows Update queries
- Report Contents: Includes computer name, username, installed software paths, hardware details
- Data Sensitivity: Reports may reveal system configuration—review before sharing
- No Telemetry: Script does not send data anywhere; purely local operation
- Auto-Download: Only downloads from official Microsoft servers (download.sysinternals.com)
- GPU Tools: GPU-Z must be downloaded manually from techpowerup.com (launcher opens browser)
- File Validation: Tool integrity verification checks digital signatures and file sizes
