DesktopInfo is a program that I have been using for years and was recently updated. It's similar to SysInternals' BgInfo but I like that it is dynamic and can easily show the computer name, uptime, and other vital statistics.
This little application displays system information on your desktop in a similar way to some other desktop information tools. Unlike others, this application looks like wallpaper but stays resident in memory and continues to update the display in real time. Uses very little memory and nearly zero cpu. Perfect for quick identification and walk-by monitoring of production or test server farms. Everything is customisable including language.
