BgInfo displays lot of information on desktop screen including: host name, boot time, CPU specs, free space, IP address, memory, OS version, service pack and much more.
By placing BGInfo in your Startup folder, you can ensure that the system information being displayed is up to date each time you boot. Once you've settled on the information to be displayed, use the command-line option /timer:0 to update the display without showing the dialog box.
