Feature of pressing Ctrl+Alt+Del is by default enabled on any network operating system that is Windows Server 2003 and Windows Server 2008. Also when a client computer is joined to a domain it inherits this feature and enforces domain users to press this key combination before they can get logon dialogue box. However if administrators want they can configure this setting on a Windows 7 computer which is either in a workgroup environment or is not connected to any network at al. This setting although adds an extra layer of security it is not recommended on home computers in order to make things easier for home users. As an administrator if you want to configure this you can follow the steps given below:
- Logon to the computer with administrator account.
- Click on Start button.
- At bottom of start menu in search box type gpedit.msc command and press enter key.
