Rainmeter

Rainmeter is the best-known and most widely used desktop customization software for Windows. Enhance your Windows PC at home or at work with skins, which are small, portable applets that float freely on your desktop. Rainmeter skins give you useful information at a glance. It's simple to monitor your system resources, such as RAM and battery life, as well as your Internet data streams, which include email, RSS feeds, and weather forecasts.

Many skins are even functional, allowing you to take notes and to-do lists, launch your favorite applications, and control your media player all from a clean, unobtrusive interface that you can rearrange and personalize as you see fit. There are thousands of skins available, created by a vast and expanding community of software users. 

What is a "skin"? Skin can be numerous things. Some skins are relatively simple, single-purpose products, such as Windows desktop gadgets or Android "widgets". Others are more complicated, such as the micro apps themselves. Some skins even come in extensive "suites" with their own tools for modifying their shape and appearance, which can be used with Rainmeter's basic user interface. Every skin operates differently, based on the preferences of the skin's inventor. 

How much technical competence is required to use Rainmeter? If all you want to do is download skins from the Internet and use them as-is, the answer is "none." Rainmeter for PC has a simple user interface for managing your skin library, saving and restoring layouts, and adjusting basic options like skin position, transparency, and "always on top" behavior. 

It features a Windows Notification Area (previously known as System Tray) icon. You may access the context menu for each of your loaded skins by right-clicking the icon. This is a useful method for accessing a skin when you are unable to right-click it. It's also a fantastic location to get a comprehensive list of all the skins you've loaded.
