Vista Meter

Developed for the Yahoo! Widget Engine, Vista Meter is a software pack which consists of two separate widgets that allow you to monitor the current CPU and memory usage of your computer. They can be seamlessly installed and configured, even by less experienced users.
The interface of the apps is based on two small frames which you can reposition to any place of the screen, with the help of the mouse cursor. They resemble two gauges and the red needles point out the current CPU and memory usage levels.
By opening the right-click menu, you can access the 'Settings' area to make several adjustments to the widgets. Therefore, you can specify the update frequency (between 1 second and 20 seconds) and switch to a different skin for the interface (e.g. Vintage, Ultimate).
With the courtesy of the default settings supplied by the Yahoo! Widget Engine, you may also make the frames stay on top or below any other window, to ignore mouse events and to prevent dragging. Plus, you can adjust their opacity level between 20% and 100%.
The widgets do not put a strain on the computer's resources, as they run on a small amount of system resources. They have a good response time and didn't freeze, crash or pop up error dialogs during our tests. All in all, Vista Meter should satisfy users of any experience level. No recent updates have been made.
