Task Manager

This repository contains an advanced Windows Task Manager application implemented in C. The application provides real-time monitoring and management of system processes, CPU, memory, and disk usage, featuring a graphical user interface with enhanced features over the default Windows Task Manager.

Features

• Process List: Displays all running processes with details such as name, PID, memory usage, thread count, CPU usage, runtime, and system status.
• End Task: Allows users to terminate selected processes directly from the interface.
• Performance Graphs: Real-time compact graphs for CPU, memory, and disk usage, showing historical data.
• Process Highlighting: Visually indicates high CPU/memory usage, long-running processes, and system processes with distinct colors.
• Thread Counting: Shows the number of threads for each process.
• Sorting: Processes are sorted by memory usage for quick identification of resource-heavy processes.
• Refresh: Manual refresh and periodic automatic updates of the process list and metrics.
• Double Buffering: Smooth UI rendering with reduced flickering.
• Custom Icons: Displays file icons for processes where available.

Getting Started

Prerequisites

• Windows OS
• MinGW or Visual Studio (for building)
• Required libraries: comctl32, psapi, pdh, uxtheme, shell32

Building

1. Clone the repository:

   git clone https://github.com/ThangakumarC/os.git
   cd os

2. Compile the taskmgr source file:

   gcc taskmgr -o TaskManager.exe -lcomctl32 -lpsapi -lpdh -luxtheme -lshell32

   Or open the project in Visual Studio and build as a Windows Desktop Application.

Running

Run the executable:

TaskManager.exe

You will see the main window with tabs, process list, and performance graphs.

Usage

• Refresh: Click "Refresh" to update the process list manually.
• End Task: Select a process and click "End Task" to terminate it.
• Performance: View live graphs for CPU, memory, and disk usage.
• Sorting & Highlighting: Resource-heavy or long-running processes are automatically highlighted.

Code Structure

• taskmgr: The main source file containing UI, process management, and system performance logic.
• Uses Win32 API for window management, process enumeration, and performance counters.
