Rainmeter has been around since Windows XP and has remained an open-source project since its inception. Skins can also be functional widgets – they can launch apps, control your media player, search the web, shut down your PC, show the music visualizer, etc. They show useful information like CPU usage, memory, RSS feeds, weather forecasts, data speed monitor, and more. Rainmeter skins expand the capabilities of your desktop to be more than just a wallpaper with a bunch of icons. Rainmeter is a free, open-source desktop customization tool that allows you to customize the look and feel of your Windows desktop. Are you bored with your standard Windows desktop? Personalize your desktop in every way you like with Rainmeter.
