Pressing CTRL+ALT+DEL and then "K" on a Windows terminal does what?
-
Warm boots the Terminal
-
Shut downs the Terminal
-
puts the Terminal in Standby
-
Locks the Terminal
The Three-Finger Salute (Ctrl+Alt+Del) opens the Windows Security screen. Pressing K at this screen immediately locks the workstation, requiring password to re-enter. Other options like warm boot (A) or shutdown (B) require different key choices from this menu.
In the classic Windows NT/2000/XP 'Windows Security' dialog raised by Ctrl+Alt+Del, each button had an underlined accelerator letter. The 'Log Off' button used 'L', so the 'Loc(k) Computer' button used the underlined 'K' to avoid a conflict. Pressing Ctrl+Alt+Del and then K therefore invokes 'Lock Computer', locking the workstation/terminal (other accelerators were U=Shut Down, C=Change Password, T=Task Manager). It does not warm-boot, shut down, or standby the machine. So 'Locks the Terminal' is correct. Note this is the legacy pre-Vista Windows Security dialog; modern Windows (Vista+) replaced it with a full-screen options menu without these same button mnemonics, but the mnemonic-based question is describing the classic dialog.
