HWdiag

HwDiag is a Windows hardware testing and diagnostics tool that identifies what is actually installed in a machine — reading SMBIOS firmware tables, the device tree, DXGI and storage controllers rather than trusting the convenient answer — then runs tiered tests across the processor, memory, graphics, storage and network, from a two-minute read-only health check to a ninety-minute stress and soak run with a thermal cut-out.

Results are presented on a dashboard as a 0–100 health index per subsystem and overall, derived from tunable per-device-class thresholds in a plain JSON file, with live charts of throughput, temperature and the score itself while a run is in progress.

Every verdict comes with a plain-English explanation and a recommended action, every number carries the coverage that earned it, and anything the tool could not measure is reported as not measured rather than as a zero — a drive that was never tested and a drive that failed every test are different claims, and the product never conflates them. It runs from a USB stick with no installation and no .NET runtime, keeping its settings, logs and reports beside the executable so a technician's evidence leaves with them, or installs to Program Files for managed desktops; a headless CLI drives the same engine for imaging lines and RMM integration, and each run exports a branded PDF report alongside JSON and CSV.
