How to Retrieve Titles and Process IDs of Taskbar Applications in C#

In this guide, learn how to obtain a list of all Windows processes with visible windows (i.e., those shown on the taskbar) using C#.
This can be particularly helpful when working with third-party tools that require the title of a specific window, such as screenshot applications.
For example, some screenshot tools may need the title of an open window to capture its content but may not provide an easy way to identify the process ID. If you're working with a C# tool and relying on command-line utilities, you can list all processes that have windows in the taskbar, allowing you to extract the title and capture a screenshot.
// 1. Import System Diagnostics using System.Diagnostics; // 2. Get a list of all active processes in Windows Process[] processList = Process.GetProcesses(); // Iterate through each process foreach (Process process in processList) { // Check if the process has a window title (indicating it appears in the taskbar) if (!String.IsNullOrEmpty(process.MainWindowTitle)) { Console.WriteLine("Process: {0}", process.ProcessName); Console.WriteLine(" ID : {0}", process.Id); Console.WriteLine(" Title: {0} \n", process.MainWindowTitle); } }
Output:
Process: chrome ID : 11896 Title: c# - get the titles of all open windows - Stack Overflow - Google Chrome Process: WinStore.App ID : 15348 Title: Microsoft Store Process: SystemSettings ID : 11020 Title: Settings Process: ApplicationFrameHost ID : 8848 Title: Settings Process: Code ID : 7852 Title: ? Untitled-2 - electron-quick-start - Visual Studio Code Process: WindowsInternal.ComposableShell.Experiences.TextInput.InputApp ID : 13864 Title: Microsoft Text Input Application Process: devenv ID : 16860 Title: Sandbox (Running) - Microsoft Visual Studio Process: Sandbox ID : 15524 Title: Form1 Process: NVIDIA Share ID : 13076 Title: NVIDIA GeForce Overlay
With this code, you can easily filter and list all the applications currently visible in the taskbar, extracting their titles and process IDs.
