Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Planned

  • HTML report export with charts and graphs
  • Baseline comparison mode (compare current vs. previous test run)
  • Skip flags (-SkipCPU, -SkipNetwork, etc.) for targeted testing
  • CSV export for data analysis
  • Memory leak detection module
  • Audio device testing
  • Intel Arc GPU support
  • Network deployment options / centralized log storage
  • Multi-language support

[2.4.0] - 2026-04-23

Fixed

Network — Latency Test

  • $targetPort was never defined, causing Test-NetConnection to receive Port=0 and throw a validation error on every run — latency test now correctly runs as ICMP-only with no port argument
  • Test-NetConnection -InformationLevel Detailed removed; it requires a valid port and is unnecessary for basic ping latency measurement
  • PsPing was called with IP:Port format instead of bare IP for ICMP mode
  • PsPing result regex was too strict — minor whitespace variations in output caused results to be silently dropped; regex now uses flexible \s* matching
  • Added debug output line showing raw PsPing tail when parsing still fails, making future diagnosis possible without re-running the test

Network — Speed Test

  • Single hardcoded Hetzner HTTPS URL failed under VPN/proxy TLS interception (Mullvad, Tailscale, corporate proxies) with no fallback — replaced with a 3-URL chain: Cloudflare, Hetzner HTTP, OVH
  • Added per-attempt SSL certificate validation bypass to handle MITM interception; bypass is scoped to the request and restored immediately after each attempt regardless of success or failure
  • Added minimum file size check (1000 bytes) to prevent a firewall error page from being recorded as a successful download result

Network — Recommendations

  • Virtual and VPN adapters (VMware VMnet, Hyper-V vEthernet, Tailscale, Mullvad, WireGuard, TAP-Windows, OpenVPN) were incorrectly flagged as "slow physical NICs" at 100 Mbps
  • Recommendation engine now iterates adapter lines individually and excludes known virtual/VPN adapter name patterns before applying the slow-speed check

Reports — Output Location

  • Reports were saving to the script root directory; now saved to a Reports\ subfolder
  • Reports\ folder is created automatically on first report generation
  • Energy report (powercfg /energy) redirected into Reports\ alongside text reports
  • Write-access test updated to target Reports\ folder; error messages now include the specific path that failed

Reports — Encoding

  • Report files written as UTF-8 caused Unicode bullets (•) and arrows (→) to render as mojibake (• â†') in Notepad and legacy text viewers
  • Switched Out-File encoding from UTF8 to ASCII throughout report generation
  • Replaced all Unicode bullet (•) characters with * and arrow (→) characters with ->
  • Removed Unicode box-drawing characters (└─) from PowerShell menu display strings
  • Script file is now fully 7-bit ASCII — no encoding surprises in any editor or viewer

Batch Launcher

  • Sysinternals Suite auto-download used a single HTTPS URL with no SSL bypass — same VPN/proxy TLS interception issue as the PS1 speed test; same fix applied
  • VERIFY section exit-code branching silently swallowed function output, producing misleading success messages regardless of actual result; simplified to direct output display
  • Stale reference to legacy SystemTester_FIXED.ps1 filename removed from error message
  • EXIT screen updated to show correct Reports\ subfolder path

[2.21.0] - 2025-09-02

Added

  • Tool integrity verification with digital signature checking for all Sysinternals executables
  • Dual report system: timestamped Clean Summary and Detailed output saved as separate .txt files
  • Batch launcher (SystemTester.bat) with reliable admin elevation and interactive menu
  • GPU Tools Manager — batch menu option 6 for managing NVIDIA, AMD, and GPU-Z testing utilities
  • Enhanced GPU testing: multi-GPU support, NVIDIA-SMI integration, AMD driver detection via registry
  • DirectX diagnostics via dxdiag, OpenGL registry check, hardware-accelerated GPU scheduling detection
  • Windows Update integration — checks pending updates, lists titles and classifications, reports service status
  • WHEA hardware event log scan covering last 7 days
  • Network speed and latency testing (initial implementation: Test-NetConnection, PsPing)
  • Launcher awareness detection — script detects if launched via batch file for context-aware messages
  • Test-OSHealth — runs DISM /ScanHealth and SFC for OS integrity (admin only)
  • Test-StorageSMART — collects health status and media type from physical disks
  • Test-Trim — checks SSD TRIM enablement status via fsutil
  • Test-NIC — captures active network adapter details including link speed and MAC address
  • Test-GPU — GPU and display configuration with DirectX and OpenGL information
  • Test-Power — battery status and powercfg /energy report generation (admin only)
  • Test-HardwareEvents — WHEA error log scan
  • Support for additional Sysinternals tools: sigcheck, contig, diskext, listdlls, clockres
  • -AutoRun parameter for unattended full-suite execution with automatic report generation
  • Color-coded console output (green/yellow/red) for all test results and recommendations
  • Recommendations engine — dynamically generated findings covering memory, CPU, disk, SMART, TRIM, network, GPU drivers, Windows Update, and WHEA events
  • GPU sub-menu options: 12a (basic info), 12b (vendor-specific), 12c (GPU memory)
  • GPU-Z download assistant with file size validation in batch launcher

Fixed

  • Memory usage calculation: FreePhysicalMemory (reported in KB) was not being converted correctly, causing inflated usage percentages

Changed

  • Admin elevation method replaced: net session check swapped for PowerShell WindowsPrincipal.IsInRole with FLTMC as fallback — more reliable on systems where the Server service is disabled
  • Interactive menu expanded to 18 options
  • Report executive summary now includes total tests, success/failure counts, success rate, and duration
  • Detailed report output cleaned and limited to first 40 lines per tool to reduce file size

[2.0.0] - 2024-11-01

Added

  • Complete rewrite with modular function structure
  • Interactive menu system with numbered options
  • Recommendations engine (initial version)
  • Improved report formatting with section headers

Changed

  • Monolithic script refactored into discrete test functions
  • All WMI calls migrated to CIM instances for better performance and PowerShell 7 compatibility

[1.0.0] - 2024-01-01

Added

  • Initial release
  • Core Sysinternals tool runner: psinfo, coreinfo, pslist, handle, clockres, autorunsc, du
  • Basic system information collection (OS, CPU, RAM, storage)
  • Single text report output
  • Manual Sysinternals installation required
