Rainmeter is a popular desktop customization tool for Windows. It will enhance your Windows computer at home or work by displaying customizable skins - handy and compact applets that float freely on your desktop. Rainmeter skins provide you with useful information at a glance. It's easy to keep an eye on your system resources, like memory and battery power, or your online data streams, including email, RSS feeds, and weather forecasts.
Many skins are even functional: they can record your notes and to-do lists, launch your favorite applications, and control your media player - all in a clean, unobtrusive interface that you can rearrange and customize to your liking. There are thousands and thousands of skins available, crafted by a large and ever-growing community of Rainmeter users.
