The DirectX Diagnostic Tool, better known as DxDiag, is a built-in Windows utility that helps you check graphics, sound, and system information. It is especially useful when troubleshooting game crashes, driver issues, or display problems.
If you need to open it quickly, Windows 11 gives you several different ways to do it. Here are five reliable methods, from the fastest shortcut to command-line options.
1. Open DxDiag with the Run Dialog
This is the quickest method for most people because it opens the tool directly with a single command.
- Press Windows + R to open the Run dialog.
- Type dxdiag.
- Press Enter or click OK.
- Wait for the DirectX Diagnostic Tool to load.
2. Search for It from the Start Menu
If you prefer using Windows search, you can launch the tool without typing a command into Run.
- Press the Windows key or click Start.
- Type dxdiag in the search box.
- Select dxdiag or DirectX Diagnostic Tool from the results.
- Open the app.
3. Open It from File Explorer
DxDiag is stored as a system file in the Windows folder, so you can open it directly from File Explorer if needed.
- Open File Explorer.
- Go to C:\Windows\System32.
- Find dxdiag.exe.
- Double-click it to launch the tool.
4. Launch DxDiag from Command Prompt
This method is useful if you are already working in a command window or troubleshooting from the command line.
- Open Command Prompt.
- Type dxdiag and press Enter.
- Wait for the tool to start.
5. Open It from PowerShell
PowerShell works the same way as Command Prompt for launching DxDiag.
- Open PowerShell.
- Type dxdiag and press Enter.
- Allow the tool to open and finish collecting system details.
What DxDiag Shows You
Once the tool opens, it displays tabs for system, display, sound, and input information. This makes it useful for checking driver versions, confirming graphics hardware, and spotting problems that may affect games or media playback.
- System details such as Windows version and processor information
- Display information for graphics adapters and drivers
- Sound device details
- Input device information such as controllers and keyboards
Which Method Should You Use?
For most users, the Run dialog is the simplest and fastest option. Search is a good alternative if you do not remember the command, while File Explorer, Command Prompt, and PowerShell are useful if you are already working in those places.
