Otherwise some remote software will provide an option to login with this key combo somewhere in its own interface. 5:38 AM in response to KSNICK In response to KSNICK.

Gates stated he would have preferred a single button to trigger the same actions, but could not get IBM to add the extra button into the keyboard layout. During a question and answer presentation on 21 September 2013, Gates said 'it was a mistake', referring to the decision to use Ctrl+Alt+Del as the keyboard combination to log into Windows. I may have invented it, but I think Bill made it famous.' he quickly added it was a reference to Windows NT logon procedures ('Press Ctrl + Alt + Delete to log on'). Bradley is also known for his good-natured jab at Gates at the celebration of the 20th anniversary of the IBM PC on Augat The Tech Museum:'I have to share the credit. Bradley viewed this work as just one small task out of many: 'It was five minutes, 10 minutes of activity, and then I moved on to the next of the 100 things that needed to get done.' In a March 2018 email, one of Bradley's co-workers confirmed the command was invented in 1981 in Boca Raton, Florida. The feature, however, was detailed in IBM's technical reference documentation to the original PC and thereby revealed to the general public.

Windows DOS-based Windows Close Program dialog box, seen in Windows 9xIn Windows 9x and Windows 3.0 running in 386 Enhanced mode, the keystroke combination is recognized by the Windows keyboard device driver. Examples of such operating systems include DOS, Windows 3.0 in Standard Mode as well as earlier versions of Windows. The BIOS reacts by performing a soft reboot (also known as a warm reboot).

If LocalReboot=Off, Windows performs a soft reboot. The user can press Control+Alt+Delete again to perform a soft reboot. Windows 9x temporarily halts the entire system and displays the Close Program dialog box, a window which lists currently running processes and allows the user to end them (by force, if necessary). The text of this rudimentary task manager was written by Steve Ballmer. Windows 3.1x displays a blue screen that allows the user 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=On (default):

(See below.) Prior to Windows Vista, Windows Security was a dialog box, did not allow user switching and showed the logon date and time, name of user account into which the user has logged on and the computer name. It is a graphical user interface that allows user to lock the system, switch user, log off, change the password, invoke Windows Task Manager, or end the Windows session by shutting down, rebooting or putting the computer into sleep or hibernation clicking 'Cancel' or pressing the Escape key returns the user to where they were.The key combination always invokes Windows Security in all versions and editions of Windows NT family except Windows XP. Winlogon, a core component of the operating system, responds to the key combination in the following scenarios:Invoking Windows Security When a user is logged onto a Windows computer, pressing Ctrl+Alt+Delete invokes Windows Security.

The Welcome Screen of Windows XP, however, does not support the secure attention scenario. Windows XP behavior Windows XP introduces Welcome Screen, a redesigned logon interface. Unless the Windows computer is part of a Windows domain network, the secure attention protection is disabled by default and must be enabled by the user. Since the key combination is intercepted by Windows itself and malicious software cannot mimic this behavior, the trick is thwarted. Once the protection is activated, Windows requires the user to press Ctrl+Alt+Delete each time before logging on or unlocking the computer. To thwart this attack, Windows NT implements an optional security measure in which Ctrl+Alt+Delete acts as a secure attention key combination.

OS/2 In OS/2, this keystroke combination is recognized by the OS/2 keyboard device driver, which notifies the session manager process. Windows Vista and the next versions of Windows NT did not inherit any of the above. When a user is logged on to a Windows XP computer and Welcome Screen is enabled, pressing the key combination invokes Windows Task Manager instead of Windows Security. At a logon prompt, the key combination dismisses Welcome Screen and invokes classic logon user interface. With that in mind, Windows XP uses the Ctrl+Alt+Delete in the following unique scenarios:

Control+ вЊ Command+ Power restarts the computer. Instead, вЊ Command+ вЊҐ Option+ Esc brings up the Force Quit panel. Mac Ctrl+Alt+Delete is not a keyboard shortcut on macOS. If it is pressed twice in succession OS/2 triggers an immediate soft reboot, without waiting for the session manager process.In both cases, the system flushes the page cache, cleanly unmounts all disc volumes, but does not cleanly shut down any running programs (and thus does not save any unsaved documents, or the current arrangements of the objects on the Workplace Shell desktop or in any of its open folders).

Perform a soft reboot without memory initialization by jumping to IPL reset vector, after broadcasting a pending shutdown event (on AT compatible machines) and flushing disk caches (since DOS 6, or with FreeKEYB loaded). Perform a soft reboot without memory initialization by jumping to IPL reset vector, after broadcasting a pending shutdown event (on AT compatible machines). Equivalents on various platforms Desktop operating systemsPerform a hardware reboot by sending a reset signal to system via keyboard MCU (+ possible extra keycode + max 10s delay if 'reset warning' is supported and in use). On Ubuntu Server, it is used to reboot a computer without logging in. Linux The result of pressing the key combination in Ubuntu v12.10On some Linux-based operating systems including Ubuntu and Debian, Control+ Alt+ Delete is a shortcut for logging out.

Perform a hard reboot by triggering the chipset's reset logic, after broadcasting a pending shutdown event and flushing disk caches. Perform a soft reboot with memory initialization (aka 'cold reboot') by jumping to IPL reset vector, after broadcasting a pending shutdown event (on AT compatible machines) and flushing disk caches. If more than one task is running under multitaskers like DR-DOS EMM386 /MULTI + TASKMGR, this will only kill the currently running foreground task. QEMM) can intercept and turn this into a quick reboot.

Performs a soft reboot if pressed twice. Bring up 'Close Program' dialog box (a simplistic task manager). Performs a soft reboot if pressed twice.
