A couple forum posts from late 2008 seemed to indicate that it wasn't possible back then. I tried CTRL-ALT-Backspace and the cursor changes to the arrow with the hourglass for a split second, but nothing happens. Unfortunately my secondary Vista64 machine goes into locked mode every 15 minutes (corporate machine). It'd be nice to unlock it without needing to hit CTRL-ALT-DEL on it's keyboard.
Primary: WinXP Pro SP3 32-bit
Secondary: Vista Enterprise 64-bit
Thanks in advance for any help.
