Thumb-drive friendly, Windows hardware health check toolkit using Sysinternals applications
A no-install PowerShell solution that runs a curated set of Sysinternals and Windows hardware diagnostics tools, then produces: Clean Summary Report (human-readable, de-noised) and Detailed Report (cleaned tool outputs). Perfect for field diagnostics, baseline health checks, and handoff reports to clients.
- 🖱️ One-click Menu or Autorun — interactive menu or
-AutoRun - 🧹 Output Cleaner — removes banners, EULA text, usage blocks
- 🧠 Comprehensive Tests — CPU, RAM, Disk, Processes, Security (Autoruns), Network
- 🗂️ Smart Reporting — timestamped Summary + Detailed TXT reports
- 📦 Fully Portable — run from USB; no install required
- 🧰 Graceful Degradation — missing tools are detected and skipped automatically
- 🔐 Robust Elevation Handling — uses SID-based check for admin rights (no reliance on
net session) - 🧭 Device-Grouped Test Mode — new
-AutoRunByDeviceoption for structured diagnostics
Windows 10/11; PowerShell 5.1+ (or PowerShell 7); Sysinternals tools placed in .\Sysinternals\ (the script auto-adds -accepteula where needed).

Admin rights are optional (some checks benefit from elevation). Reports include computer name and username—review before sharing outside your org. Autoruns/Streams can reveal executable paths—treat reports as sensitive artifacts.
