How to replace Ctrl+Alt+Del (taskmanager) with different application

We can launch any application when pressing Ctrl+Alt+Del instead of Taskmanager. Just these steps:

1. Go to START then click RUN. Type regedit then press enter.

2. Navigate through HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options.

3. Right click Image File Execution Options then select New then click Key. And name it Taskmgr.exe

4. Click the key that you've created (taskmgr.exe), then at the right side part of the window, right click then select New then click String Value. Then name it debugger.

5. Double Click it(debugger), then put in the location of the application (including the filename) that you want to launch every time the user press Ctrl+Alt+Del. Example: c:\windows\system32\calc.exe

6. Click Ok.

After that when you press Ctrl+Alt+Del your application will launch instead of Taskmanager.

If you want to restore it, just delete taskmgr.exe in the registry by navigating to: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options.Then double click the Image File Execution Options, the right click the Taskmgr.exe then select delete.

Thats all!
