Thank you, thank you, thank you!!! I've been searching online for HOURS to find a way to add a taskbar shortcut for my screensaver settings, as I'm constantly adjusting the "kick-in" time between 1 minute when I'm away and 15 minutes when I'm present. This worked beautifully and now I can get to this screen in one click vs. four (show desktop+right click+personalise+screensaver)!
For any Vista users out there- I'm using Vista Home Premium 32 bit and these instructions worked flawlessly. I guess even though Vista has gotten trashed, Windows 7 is basically an upgraded Vista, as all the command prompts were identical.
