The User Account Control (UAC) prompt is a security feature in Windows that asks for the user's permission before allowing certain actions that require administrative privileges. The UAC prompt typically appears when an application or process tries to make changes that affect system settings or files.

The editor used by the UAC prompt is determined by the user's default text editor setting in their environment variables. To set the default editor for the UAC prompt, you can modify the %EDITOR% environment variable. Here's how you can do it:

  1. Open the "System Properties" window by pressing Win + Pause/Break or right-clicking "This PC" or "Computer" and selecting "Properties."

  2. Click on the "Advanced system settings" link on the left side of the window.

  3. In the "System Properties" window that appears, click on the "Environment Variables" button.

  4. In the "Environment Variables" window, under "User variables for [YourUsername]," click on "New."

  5. Enter EDITOR as the "Variable name."

  6. In the "Variable value," provide the path to the text editor you want to use. For example, if you want to use Notepad as the editor, you can enter C:\Windows\System32\notepad.exe.

  7. Click "OK" to save the new environment variable.

After setting the EDITOR environment variable, the UAC prompt will use the specified text editor when displaying the contents of files that require elevated privileges for editing.

Please note that modifying system settings, including environment variables, might require administrative privileges and trigger the UAC prompt. Be cautious when making changes to the system environment variables. If you're unsure about the changes you're making, it's always a good idea to consult with a knowledgeable administrator or IT professional.
