 Your WebView2 control must open the Chrome Developer Protocol (CDP) port to allow debugging of the WebView2 control.  Your code must be built to ensure that only one WebView2 control has a CDP port open, before starting the debugger.
 
-You will also need to add a new REGKEY `*--remote-debugging-port=9222` under `Computer\HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments` so that the debugger can find the proper port. To add this registry key:
+You also need to add a new REGKEY `<myApp.exe> = --remote-debugging-port=9222` under `Computer\HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments`, so that the debugger can find the proper port.  To add this registry key:
+
+1. Press the **Windows logo key** and then search for **registry editor**.  Open the **Registry Editor** app, and then click **Yes** to allow editing.
+
+1. In the folder tree on the left, try to expand `HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments`.
+
+1. If the `\Edge\WebView2\AdditionalBrowserArguments` part of that path doesn't exist, create those three nested subfolders, as follows:
+
+   1. To create the `\Edge` subfolder: In the folder tree, right-click the `HKEY_CURRENT_USER\Software\Policies\Microsoft` folder, hover over **New**, and then select **Key**.  A folder is added as a child of the `Microsoft` folder, initially named `New Key #1`.  Right-click the `New Key #1` folder, and then select **Rename**.  Enter `Edge` for the name of the new key.
 
-1. Open the Registry Editor by pressing the **Windows logo key** and then searching for **registry editor**. Open the **Registry Editor** application, and then select **Yes** to allow editing.
+   1. Create the `\WebView2` subfolder, as in the previous step.
 
-1. Set the registry key `HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments` equal to `--remote-debugging-port=9222`.
+   1. Create the `\AdditionalBrowserArguments` subfolder, as in the previous step.
 
-   To do this, in the editor, navigate to `HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments` by clicking on each subfolder under the path.
+      The tree is now expanded to `HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments`.
 
-   If this path doesn't exist, navigate to `HKEY_CURRENT_USER\Software\Policies\Microsoft` in the editor, right-click the `Microsoft` folder, select **New**, and then select **Key**.  Enter `Edge` for the name of the new key.  Continue to do this for each subfolder until you have the full path: `HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\WebView2\AdditionalBrowserArguments`.
+1. Right-click the `AdditionalBrowserArguments` folder, hover over **New**, and then select **String Value**.  In the **Name** column, right-click `New Value #1`, select **Rename**, and then enter the file name of your app executable, such as `myApp.exe`.
 
-1. Right-click the `AdditionalBrowserArguments` folder, select **New**, and then select **String Value**.
-Rename `New Value #1` to `*`.
+1. In the **Name** column, right-click your executable file name, such as `myApp.exe`, and then select **Modify**.  The **Edit String** dialog opens.
 
-1. Right click the **\*** value, and then select **Modify**.  Set the `Value Data` equal to `--remote-debugging-port=9222`.  Verify that the edit window matches the following:
+1. In the **Value data** text box, enter `--remote-debugging-port=9222`:
