How to Enable JIT Debugging on Windows 11

Enabling JIT (Just-In-Time) debugging on Windows 11 can save you from the frustration of an application crash without any clue about what went wrong. By switching on JIT debugging, you can directly debug your apps when they run into issues. The process involves changing a few settings in Visual Studio and Windows Registry. Here’s a quick guide to get you started.

How to Enable JIT Debugging on Windows 11

In this section, we’ll walk through the steps you need to follow to enable JIT debugging on your Windows 11 machine. It involves making changes in Visual Studio and tweaking the Windows Registry. Let’s dive in!

Step 1: Open Visual Studio

First, open Visual Studio on your computer.

Visual Studio is where you will make some of the necessary changes. If you don’t have it installed, you’ll need to download and install it first.

Step 2: Go to the Tools Menu

Second, in Visual Studio, navigate to the "Tools" menu and click on "Options."

This menu contains many options related to programming and debugging settings.

Step 3: Select the Debugging Category

Third, in the Options window, expand the "Debugging" category.

The Debugging category contains various settings that control how debugging is handled in Visual Studio.

Step 4: Click on the Just-In-Time Option

Fourth, within the Debugging category, click on the "Just-In-Time" option.

Here, you’ll find settings specifically for enabling or disabling JIT debugging.

Step 5: Enable JIT Debugging

Fifth, check the boxes next to Managed, Native, and Script.

These options enable JIT debugging for different types of code.

Step 6: Click OK

Sixth, click the "OK" button to save your changes.

Your settings will now be updated to enable JIT debugging.

Step 7: Open the Windows Registry Editor

Seventh, press Win + R, type "regedit," and hit Enter to open the Windows Registry Editor.

The Registry Editor lets you view and edit keys and values in the Windows Registry.

Step 8: Navigate to the AeDebug Key

Eighth, navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionAeDebug.

This is where you will set up the necessary registry values for JIT debugging.

Step 9: Modify the Auto Value

Ninth, double-click the "Auto" value and set it to 1.

Setting this value to 1 enables automatic JIT debugging.

Step 10: Modify the Debugger Value

Tenth, double-click the "Debugger" value and set it to the full path of the Visual Studio debugger.

This tells the system which debugger to use when an issue occurs.

After you complete these steps, JIT debugging will be enabled, meaning you’ll have the ability to debug applications right when they fail, giving you the chance to fix issues on the spot.

Tips for Enabling JIT Debugging on Windows 11

  • Always back up your registry before making any changes.
  • Ensure Visual Studio is updated to the latest version for better compatibility.
  • Use descriptive names for your registry keys to avoid confusion.
  • Test JIT debugging with a small application to make sure it’s working.
  • Keep your debugging environment secure to prevent unauthorized access.
