Windows Vista includes a new console called Performance Information and Tools The console essentially gives you performance information about your system and has links to other tools in Windows, such as Software Explorer in Windows Defender, Power Settings, and so forth Click Start | Control Panel | Performance Information And Tools to access the console, shown in Figure 10-1 You ll notice here that the main thrust of the console is to provide you with a Windows Experience Index base score In the example in Figure 10-1, the score is 30 This score comes from subscores for other components of the system, as you can see in the figure Your Windows Experience Index base score is determined by your lowest subscore, which in my case is a 30 for the graphics card s performance In other words,

the lowest subscore gives you the index not an average of the subscores Essentially, the score is designed to give you information about your computer s capacity both in terms of hardware and software configuration to be able to perform well when running resource-intensive tasks Notice that you can click the Update My Score button and Windows Vista will run the Windows Experience Index again You don t need to do this unless you have changed some hardware on the system Also notice that you can view software online that is compatible with your base score The overall goal is for software developers to begin rating software according to the Windows Experience Index This way, if you re thinking about purchasing a software product, you can look on the package and find the base score If the software requires a Windows Experience Index base score of 25 and your computer has a 3, then you know you can run the software with good performance One helpful item with the console is the View And Print Details link If you click this option, you get a printable page of the detail scores, but also a quick rundown of each component This way, if you re thinking of a hardware upgrade, you can quickly see what you have at the moment, as shown in Figure 10-2

So, what can your computer do with its base score For example, let s say that you have several Windows Vista computers in your office You check the base score of each, and now you want to use the computers in a way that their current base scores will meet your needs without hardware upgrades The following sections give you a quick overview of what your computer can and can t do in terms of performance based on the score
