How to Send Ctrl-Alt-Del on VNC

Virtual Network Client, commonly known as VNC, is a free and open-source software package for remotely displaying and controlling another computer. There are many different versions of VNC available from software developers, some paid, some free. Because VNC has to run on a host computer, sending multiple key presses sometimes fails. For example, pressing "Control" "Alt" and "Delete" while in a VNC window causes the host Windows machine to open the CAD menu, not the computer controlled by VNC. Some VNC clients display a "Send Control-Alt-Delete command" button, but for those that don't, there are a few standard methods.

• 1

  Turn on your computer and log in. Launch your version of VNC viewer and connect to the host computer.

• 2

  Search the menu bar for the "Send Control-Alt-Delete" command button. depending on your version of VNC, this may be labeled "Cont Alt Del," "CAD" or simply a graphical button with three raised squares. If this doesn't send the command, or you can't find the button, proceed to Step 3.

• 3

  Right-click the action button (the program icon that sits next to the window title) for your version of VNC. Select "Send Control-Alt-Delete" (this may be worded differently in your version). If this doesn't send the command, or you can't find the menu item, proceed to Step 4.

  Hold down the "Shift" key with one finger. While keeping the shift key down, press the "Control," "Alt" and "Delete" keys in sequential order. Release the keys.
