What is the Windows Experience Index?

October 15, 2008

The Windows Experience Index measures the capability of your computer’s hardware and software configuration and expresses this measurement as a number called a base score. A higher base score generally means that your computer will perform better and faster than a computer with a lower base score, especially when performing more advanced and resource-intensive tasks.

Each hardware component receives an individual subscore. Your computer’s base score is determined by the lowest subscore. For example, if the lowest subscore of an individual hardware component is 2.6, then the base score is 2.6. The base score is not an average of the combined subscores.

You can use the base score to confidently buy programs and other software that are matched to your computer’s base score. For example, if your computer has a base score of 3.3, then you can confidently purchase any software designed for this version of Windows that requires a computer with a base score of 3 or lower.

The base scores currently range from 1 to 5.9. The Windows Experience Index is designed to accommodate advances in computer technology. As hardware speed and performance improves, higher base scores will be introduced. However, the standards for each level of the index stay the same. For example, a computer scored as a 2.8 will remain a 2.8 unless you decide to upgrade the computer’s hardware.

To view your computer’s base score:

1. Open Performance Information and Tools by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Performance Information and Tools.

2. View the Windows Experience Index base score and subscores for your computer. If you have recently upgraded your hardware and want to find out if your score has changed, click Update my score. If you don’t see subscores and a base score, click Score this computer.

Here are general descriptions of the kind of experience you can expect from a computer that receives the following base scores:

# A computer with a base score of 1 or 2 usually has sufficient performance to do most general computing tasks, such as run office productivity applications and search the Internet. However, a computer with this base score is generally not powerful enough to run Windows Aero, or the advanced multimedia experiences that are available with Windows Vista.

# A computer with a base score of 3 is able to run Windows Aero and many new features of Windows Vista at a basic level. Some of the new Windows Vista advanced features might not have all of their functionality available. For example, a machine with a base score of 3 can display the Windows Vista theme at a resolution of 1280 × 1024, but might struggle to run the theme on multiple monitors. Or, it can play digital TV content but might struggle to play High Definition Television (HDTV) content.

# A computer with a base score of 4 or 5 is able to run all new features of Windows Vista with full functionality, and it is able to support high-end, graphics-intensive experiences, such as multiplayer and 3?D gaming and recording and playback of HDTV content. Computers with a base score of 5 were the highest performing computers available when Windows Vista was released.
