![]() Theoretically, the system's other processes should continue normally-in practice, using this key combination to terminate a program/process will result in "secondary damage" that may destabilize the system. Killing tasks/processes is useful, for instance, if a program has entered an infinite loop. Windows 95, and its successors, present a window which lists currently running processes, and can be used to manually "kill" them.Windows 3.x presents a blue screen to the user inviting them to press Enter to end the current task or press Control-Alt-Delete again to restart the computer.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 DOS-based Windows (including both Windows 3.x and its successors Windows 95, Windows 98, and Windows Me), this keystroke combination is recognised by the Windows keyboard device driver. On a PC running DOS or a system that runs in real mode, this keystroke combination is recognised by the keyboard handling code in the BIOS and treated as the 80x86 non-maskable-interrupt signal, which, unless the system is horribly hung, invokes a soft reboot. David 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 really famous."Ĭolloquially, the combination is also known as a three-finger salute, or more esoterically, a Vulcan nerve pinch. 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 impossible to press with just one hand (this is not true of later keyboards, such as the 102-key PC/AT keyboard). Bradley originally designed Control-Alt- Escape to trigger a soft reboot, but he found it was too easy to bump the left side of the keyboard and reboot the computer accidentally. This keyboard combination was designed by David Bradley, a designer of the original IBM PC. It is given by simultaneously pressing the Control, Alt, and Delete keys. To use the commands available when you press Ctrl+Alt+Del, click your user tile and choose an option.Ī workaround for this is to press and hold + keys on the physical keyboard in front of you and then finally press the key on the on-screen keyboard.A humorous image created as a parody of Control-Alt-DeleteĬontrol-Alt-Delete (often abbreviated to Ctrl-Alt-Del) is a computer keyboard command on IBM PC compatible systems that can be used to reboot the computer. Under certain Windows versions the method above (using ++ in the on-screen keyboard) don't work. On-screen keyboard is a virtual keyboard inside Windows It does not work! By using the on-screen keyboard (which has been a part of all Windows versions!) the ++ keys can be toggled in the virtual on-screen keyboard. Some Remote Desktop tools offer a "CTRL-ALT-DELETE" toggle but even with the default Remote Desktop from Windows, there's a way. CTRL+Alt+Delete toggles the physical Operating System ![]() In the case of Linux Mint, a window pops up and asks whether to switch the current user or lout out of the (Linux) machine. Windows requires the Ctrl+Alt+Delete combination to change the password.īut if you're running Linux and use Remote Desktop, the ++ combo results in a command to the Linux OS. But what if you need to change your password? The Windows settings might require you to send ++ instead of clicking a button: The Change button is greyed out. Depending on your organization, you might work remotely on a Windows system, using Remote Desktop.
