Windows系统下替代xwininfo的窗口进程查询工具及GUI窗口归属程序判定方法

Great question! Since you're used to using xwininfo on Linux to map GUI windows to their parent processes, let's cover the Windows alternatives and reliable methods step by step.

1. Is there a Windows equivalent to Linux's xwininfo? #

Absolutely! The closest built-in tool is Spy++, a utility from Microsoft that lets you inspect windows, controls, and their associated processes—just like xwininfo does on Linux.

Spy++ comes included with Visual Studio (look for it in the Visual Studio Tools folder), but you can also grab standalone versions if you don't have VS installed. Once open, click the "Find Window" button (the binoculars icon), drag the crosshair to your target GUI window, and it’ll display detailed info including the window’s process ID (PID) and the executable name of its parent process.

For command-line enthusiasts, PowerShell has native capabilities that replicate xwininfo’s core functionality (more on that in the next section).

2. Reliable methods to identify a GUI window's associated program on Windows #

Here are proven, easy-to-use methods depending on whether you prefer GUI tools or command-line workflows:

• Spy++ (Built-in/Visual Studio Tool)
  As mentioned above, this is the direct equivalent to xwininfo. It not only shows the process owning the window but also lets you dig into window hierarchies, system messages, and more—perfect for deep window analysis.

• Process Explorer (Sysinternals Tool)
  This is a far more powerful alternative to the default Task Manager. Open Process Explorer, press Ctrl+F to bring up the "Find Window" dialog, drag the target icon to the GUI window you want to inspect, and it’ll instantly highlight the corresponding process in the main window. You can right-click the process to view its full executable path, memory usage, and other granular details.

• Task Manager (Built-in)

  • Open Task Manager via right-clicking the taskbar > Task Manager, or pressing Ctrl+Shift+Esc.
  • Head to the Details tab, right-click any column header, select "Select columns", and check "Window Title". Now you can sort or search for the window’s title to find its associated process.
  • Alternatively, in the Processes tab, if you can see the app listed, right-click it and select "Go to details" to jump directly to its process entry.

• PowerShell Commands
  If you prefer scripting or command-line work:

  • To find a process by window title (replace "Your Window Title" with the actual title snippet):

    Get-Process | Where-Object {$_.MainWindowTitle -like "*Your Window Title*"}
    

  • For precise window-to-PID mapping using Windows API calls (great for the currently active window):

    Add-Type @"
    using System;
    using System.Runtime.InteropServices;
    public class Win32 {
        [DllImport("user32.dll")]
        public static extern IntPtr GetForegroundWindow();
        [DllImport("user32.dll")]
        public static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId);
    }
    "@
    $hwnd = [Win32]::GetForegroundWindow()
    [Win32]::GetWindowThreadProcessId($hwnd, [ref]$pid)
    Get-Process -Id $pid
    

• Command Prompt's tasklist
  Use the /v flag to show verbose info including window titles, then filter results with findstr:

  tasklist /v | findstr "Your Window Title"
  

  Note: This might return multiple results if the title is generic, so cross-reference with other details like PID to narrow it down.
