Using the new 'resource overview' monitor in Windows Vista

The Windows performance monitor has received a considerable facelift with the release of Vista, and now offers a whole host of monitoring information about your computer, once you've learned how to configure it for easy use. The most obvious and useful new feature is the resource overview window. This screen handily centralizes your CPU, memory, network and hard disk % at use information and allows you to track which files and processes are using your system resources in real-time. Let's take a look at how to use it.

To open the resource overview screen:

Open the 'start' menu and type 'monitor' in the search box and hit Enter.

Welcome to the new and improved resource overview screen. As you can see, the four windows correspond to the four major hardware areas of your system, and show you essentially how hard they are working over the last 60 seconds of time. Now, let's dig a little deeper.

If you double click on any of the four displays, you'll notice that the corresponding heading on the lower part of the screen will expand, offering you more information. For the CPU, we can see exactly which processes have been taking up CPU time over the last minute, and what percentage. For the hard drive, the files that have been read from and written to and how much. For the network which processes are accessing network connections and how much data are they transferring (very useful for identifying possible spyware/trojan virus problems), and for the memory you can see how much memory each running process is consuming and what percentage of that can be shared with other applications or is fully reserved. All-in-all a very useful overview of the activities of your entire computer system right at your fingertips.
