A tiny Win32 application (C++) that displays the system's up-time either in a small (transparent) window on your desktop or in a tool tip whenever you hover over the UpTime 2000 icon in the system tray.
Unzip the uptime2k.zip archive into a new directory. Run the uptime.exe file and you should see the UpTime icon appear in the system tray immediately. Add it to your startup folder to always have the icon in your tray. Right-click the tray icon and set the options as you like. To move the display around your desktop you should turn transparency off, move it to where you want it to be, and then turn transparency on once again. You can now save your settings and every time UpTime 2000 starts up it'll use them automatically. Once you've positioned it where you want it and set the colors appropriately, you should click the 'remember settings' option. If you place a shortcut to the app in your startup folder, it'll start up the same way every time you restart your machine.
