Open Registry Editor by typing regedit in RUN command. After opening it find for the following :

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

On the right pane look for DisableTaskMgr & look what values are given:

1 – Disable task manager
0 – Enable task manager

Change the key according to you... & if you delete it the default setting will be done...!

To Enable or Disable the CTRL+ALT+DELETE Sequence

1. Click Start, click Control Panel, and then click User Accounts.
2. Click the Advanced tab.
3. In the Secure logon section, select or clear the Require users to press Ctrl+Alt+Delete check box.

Note If the Advanced tab is not available, click Start, click Run, type control userpasswords2, and then click OK.
