That's Windows-key (between ctrl and alt on most keyboard) + L. A standard feature of XP. Like Windows-key + M = minimize all windows (and show desktop) and Windows-key + E = start My Computer.
I'm using Windows XP Professional.
I have in mind doing some sensitive work when someone comes in whom I don't want looking at what I'm doing. Or maybe I've got to get up from my work all of a sudden, and don't want someone stumbling across the laptop and getting curious.
I have been using my regular old Windows screen saver program, set to "Marquee" with a black background and no text. It's set to ask for a password on resume, and I have a shortcut on my desktop so all I have to do is hit Ctrl+Alt+F12 and I'm on a black screen.
The problem is: for some reason with this screensaver setup, it doesn't always ask for the password on resume. If I leave it sit for several hours with the black screen up, it does, but if I only leave it for thirty seconds or so, it doesn't.
I do not care particularly about the aesthetics here... it doesn't have to be a black backdrop, if I could figure out how to get straight to the login screen instead, maybe, that would be fine. But I really want it to be password-protected, and it has to be something I can do with just a very quick keystroke.
Any help would be seriously appreciated. Thanks ahead of time.
