CapFrameX is a performance capture and analysis tool designed for PC gamers and benchmarking enthusiasts, which records frametimes, frame-rates and various sensor data during game or application execution. It uses backend tools like PresentMon to log data and then exposes a comprehensive UI for analyzing the results: you can view charts of frametimes, historic graphing, stuttering analysis, L-shape graphs, input-lag overlays, and compare multiple capture runs side by side. Importantly, the tool also integrates with sensor inputs (CPU, GPU, VRAM, temps, etc.) and overlays statistics in-game via Rivatuner Statistics Server, so you get in-situ feedback while you run. For benchmarking, it supports aggregation, filtering, outlier detection, and export of records to CSV/Excel for further analysis or reporting. The project is suited for reviewers, hardware testers, and power users who want to dig deeper than simple FPS numbers and want to diagnose performance issues.

Argus Monitor is a powerful fan-control and system-monitoring tool that gives you complete control over cooling behavior across your entire PC. It allows you to manage CPU, GPU, motherboard, and AIO fans using fixed values or advanced temperature-based control curves sourced from any sensor in your system. With multi-controller support, fan profiles, hysteresis, and temperature averaging, Argus Monitor offers smooth, precise fan adjustments with minimal noise fluctuation. The software also includes robust temperature monitoring for CPUs, GPUs, SSDs, RAM, and additional sensor channels. For supported devices, it provides RGB control as well as gadget and tray-icon displays for quick system insights. Lightweight, stable, privacy-respecting, and fully customizable, Argus Monitor is one of the most comprehensive PC cooling and monitoring solutions available.

SIV by Ray Hinchliffe. 'System Information Viewer' is a general Windows utility for displaying lots of useful Windows, Network and hardware info - CPU info, PCI info, PCMCIA info, USB info SMBus info, SPD info, ACPI methods, Machine info, Hardware Sensors, Networked computers, Operating System Information and more. SIV is designed for Windows 11, 10, 8, 7, Vista, XP, 2012, 2008, 2003, 2000 and NT4. Windows 95, 98 and Me are also supported. SIV can also be used to control AIO devices, such as fans and LEDs. To do this, you need to specify the -AIOCTL command line qualifier. When -AIOCTL is specified, SIV will automatically do the EnhancedPowerManagementEnabled registry change and restart the USB device. SIV (System Information Viewer) uses pcidevs.txt for the PCI devices, usbdevs.txt for the USB devices, and mondevs.txt for monitoring pcmdevs.txt PCMCIA device descriptions.

SysGauge is a powerful system monitoring and performance analysis tool for Windows that delivers deep insights into your computer’s operation. It provides real‑time visualization of key metrics across multiple domains: CPU and memory usage, disk I/O, network traffic, and active processes. The application features a customizable dashboard with live graphs, gauges, and tables, letting you track trends and spot bottlenecks at a glance. SysGauge supports historical data logging for post‑analysis and capacity planning, and offers alerting for critical conditions (e.g., high CPU load, low disk space). It includes advanced process monitoring with detailed resource breakdowns, service status checks, and network connection tracking.

Pachtop is a fast, open-source system monitoring application that provides a modern and elegant way to view your computer’s performance. Built with Rust, Tauri, and React, it delivers real-time insights into CPU, RAM, disk, and network usage while remaining lightweight and responsive. Designed for Windows, macOS, and Linux, Pachtop displays both system metrics and running applications in a clean, intuitive interface. Users can easily track resource consumption, analyze storage, and check detailed hardware and OS information. With its cross-platform foundation and MIT license, Pachtop is ideal for developers, IT professionals, and power users who want transparency, speed, and full control — all in one visually appealing desktop tool.

The above dashboard captures: - Power consumption of the CPU and GPU - CPU voltages and frequencies - Load breakdown on individual GPU components - CPU, GPU, disk, and motherboard temperature readings - Disk activity, space remaining, and error monitoring - Fan speed - Network consumption

VRPN, Virtual Reality Peripheral Network, is a device-independent and network-transparent system for accessing virtual reality peripherals in VR applications. The project generates a dll to easily conect a C# aplication with the VRPN server.

A client side framework that provides agent-less remote access to CIMOMs regardless of the CIMOM communication protocol. Main components: Extensible protocol adapter framework, Dynamic discovery of server protocol. ( CIM, WBEM, WMI, OpenWBEM )

Manage and configure multiple routers from a single interface. Project is aimed at becoming a suite of utilities for Cisco network management. Mainly tested on: Cisco 1841 (revision 6.0) with 236544K/25600K bytes of memory.

Just a place to collect & share the scripts I've developed as an MSP for my various software systems, like PSA & RMM... and more from other like-minded MSPs who wanted to help others! No guarantee that everything is in PowerShell, C#, or even the latest version, so be sure to read the code comments and other documentation, as well as ask the community. You may even find discussions. -pat
