This is the default behavior in Windows Vista and Windows Server 2008, regardless of whether or not the computer is part of a domain. If the computer is configured as a part of a domain or it runs Windows 2000, the combination brings up the "Windows Security" dialog, where the user can lock the computer, change their password, log out, shut the computer down, or invoke the Task Manager.Also used when the computer is locked to bring up the unlock dialog. If nobody is logged in, bringing up the login dialog to allow the user to log in.In Windows NT, and thus on its successors, including Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008 and Windows 7, this keystroke combination is recognized (as a special system-wide "keyboard hook") by the Winlogon process, which in response instructs GINA to perform one of the following tasks: However, this functionality does not always work. This allows the user to over-ride any "stuck" process, since no user-level program is able to define its own response to the Control-Alt-Delete key combination. In Windows 9x, pressing the combination a second time if the process listing has not appeared will display a blue screen from which the user can reboot the system by pressing the combination a third time other times the system restarts on the second Ctrl-Alt-Delete combination. Such damage is much less likely in newer versions of DOS-based Windows because of resource tracking. As such, it is strongly recommended that, following a process kill in these versions of Windows, any work should be saved in any other applications and Windows should be restarted. Theoretically, the system's other processes should continue normally-in practice, using this key combination to terminate a program/process in Windows 3.1 can result in resources and memory being leaked. Killing tasks/processes is useful, for instance, if a program has entered an infinite loop.
The user can press Control-Alt-Delete again to perform a soft reboot. Windows 95, Windows 98, and Windows Me, temporarily halts the entire system, and presents a window which lists currently running processes, and can be used to notify them that they should end, or, when they don't respond, kill them.Windows 3.1x presents a blue screen to the user inviting them to press Enter to end a task that has stopped responding to the system (if such a task exists) or press Control-Alt-Delete again to perform a soft reboot.If LocalReboot=Off it performs a soft reboot.According to the value of the LocalReboot option in the section of system.ini, Windows performs one of several actions in response: In Windows 3.1x running in 386 Enhanced mode, Windows 95, Windows 98, and Windows Me, this keystroke combination is recognised by the Windows keyboard device driver. The "Close Program" window in Microsoft Windows 95, 98, and ME.

However, while Bradley implemented the key sequence in the ROM BIOS, he did not suggest it the team of the then chief programmer of the IBM PC Project, Mel Hallerman, did. He afterwards elaborated that it was made more famous due to Windows NT logon procedures ("Press Ctrl + Alt + Delete to log on"). Bradley is also known for his good-natured jab at Bill Gates, at that time the CEO of Microsoft, and also the creator of many of Microsoft's programs: "I may have invented Control-Alt-Delete, but Bill Gates made it famous". More advanced operating systems use its status as a "reserved" combination for various purposes, but often retain the ability to trigger a soft reboot in certain configurations or circumstances. He switched the key combination to Control-Alt-Delete, a combination that was impossible to press with just one hand (this is not true of later keyboards, such as the 102-key PC/AT keyboard or the Maltron keyboard). Bradley originally designed Control-Alt- Escape to trigger a soft reboot (without warning or confirmation by the user), but he found it was too easy to bump the left side of the keyboard and reboot the computer accidentally. This keyboard combination was invented by David Bradley, a designer of the original IBM PC.
