- Open regedit.exe and navigate to:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
- Create a folder (key) called Narrator.exe
- Inside the key, create a new String value called Debugger, and set its value to %1
- Close registry editor
From now on, every time Windows will attempt to execute Narrator.exe, nothing will happen!
If you need Narrator.exe back, just remove the Narrator.exe registry key.
