StatBar is a freeware system status bar which allows you to quickly get an overview of your system's condition (memory, CPU, uptime, and much more).
In the most recent version, these modules are available: battery status, CD door eject/close, CPU usage, Dial-Up Networking status, exit/lock buttons, hard disk information, locks status, master volume control, memory status, network traffic meter, Quick Launch, RC5/OGR counter, time synchronization, Winamp controls, Windows uptime, and Windows version. You can set the order in which StatBar displays its information modules yourself; you can control the alignment of the modules, display or hide the separators and the module name labels, etc. Display StatBar either in dark gray, dark blue, dark red, Win2K/ME-style gray, WinXP-style silver, or WinXP-style blue. StatBar can be displayed either at the top or at the bottom of your screen. It has an auto-hide option, which can be configured to either pop up the bar on a mouse move or on a mouse click. The window position, auto-hide state and color scheme can all be changed via the right-click popup menu with just a few mouse clicks. StatBar can check if there is a new version available for download from the internet. If so, the program can download and install the update for you.
