Until Windows XP, the Ctrl+Alt+Del shortcut, was used to open the Windows Task Manager. But from Windows Vista onwards it was changed to open a new Ctrl+Alt+Del screen with consisted of options such as locking or logging off, starting the Task Manager etc. In Windows 7 and Windows Vista, to open Task Manager you now have to press Ctrl+Shift+Esc.
Using the Group Policy Editor in Professional and above latter versions of Windows, you can easily modify the Ctrl+Alt+Del screen to include only the options that you want. Here’s how to do it via Group Policy.
First open the Start menu and type gpedit.msc. Press Enter. This will open the Group Policy Editor.
Now navigate down to User Configuration > Administrative Templates. You will find a System sub folder under Administrative Templates. Click on it and in the right pane you will be able to see Ctrl+Alt+Del Options as shown below. Double click that.
Now you will see the available options that you can customize in the right pane.
Remove Change password – If you enable this, the Ctrl+Alt+Del screen will not show the Change Password option.
Remove Lock Computer – If you enable this, you will not be able to lock the computer from the Ctrl+Alt+Del screen.
Remove Task Manager – If you enable this, it will remove the Start Task Manager option from the Ctrl+Alt+Del screen.
Remove Log Off – This option will remove the Log Off option from the Ctrl+Alt+Del screen.
Just double click the setting that you want to change. Select Enabled or Disabled as you wish and click OK.
You can see the changes immediately by pressing Ctrl+Alt+Del.
