The Microsoft Windows operating system comes installed with what is referred to as the "system debugger." The system debugger was known as the "Dr. Watson" application in earlier versions of the Microsoft Windows operating system. The system debugger can sometimes cause problems for your system if it encounters errors, which can negatively impact the performance of your computer system. In this case, you can disable the system debugger by editing the Windows registry.

Skill level:
Moderately Easy


  1. 1

    Click the Windows "Start" button.

  2. 2

    Click "Run" to open the "Run" prompt box.

  3. 3

    Type "regedit" (without quotes) into the "Run" text field and click "OK." This will open the Microsoft Registry Editor.

    "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AeDebug"
