Question: 1 / 570

What shortcut is used to lock Windows-based computer systems?

CTRL-ALT-DELETE

Locking a Windows-based computer system can efficiently safeguard the user's session, preventing unauthorized access while allowing for a quick return to the desktop when needed. The shortcut that enables this feature is typically CTRL-ALT-DELETE. This combination brings up the Windows Security screen, from which users can select the option to lock their computer.

Though there are other keyboard shortcuts available for various functions in Windows, they serve different purposes. For instance, CTRL-SHIFT-ESC is used to open the Task Manager directly, which allows you to monitor system performance and processes. ALT-TAB is a useful shortcut for switching between open applications, making it easier to multitask, while CTRL-ESC opens the Start menu. None of these alternatives provide a direct method to lock the computer, making CTRL-ALT-DELETE the correct and most efficient choice for this action.
