What is the Windows Experience Index ?

Performance index Windows measures the ability of hardware and software configuration of your computer and expressed by a number called Basic Index. A high base number usually indicates that your computer will perform better and be faster , especially when performing advanced tasks that request many resources, a computer with the core index is lower.

Each hardware component receives an subindex individual. The base index of your computer is determined by the sub -index lower. For example , if the sub -index down more of a hardware component is 2.6, while the core index is 2.6 . The base index does not the average for sub- indices combined. However, the sub - indices can tell you the level of performance possible components that you attach the greatest importance and help you choose which components to upgrade.

The core index allows you to purchase programs and other software compatible with the base index of your computer. For example , if the core index is 3.3 on your computer , you can buy software designed for this version of Windows which require a computer with a maximum core index is 3 .

The index currently range from 1.0 to 7.9 . Index Performance Windows is designed to support improvements in computer technology . As as the performance and speed of the hardware improves, the basic indices higher will be introduced . The standards for each index level are generally identical. However, in some cases, new tests can be developed and generate indexes lower.

Performance Information and Tools

To view the base index of your computer
  1. To open Performance Information and Tools , click Start , Then Panel. In the search box, type Performance Information and ToolsThen, in the results list , click Performance Information and Tools.

  2. Display the basic index and sub - indices of the performance index Windows for your computer . If you recently upgraded your hardware and want to know if your index has changed , click Rerun evaluation. If you are prompted for an administrator password or confirmation , provide the password or confirmation . If a base index and sub- indices are not visible , click Evaluate this computer. If you are prompted for an administrator password or confirmation , provide the password or confirmation .

About the base index of your computer

The base index represents the minimum performance of your system, and is set against the capability of different components of your computer, including memory (RAM ) , central processing unit ( CPU ) , hard disk , graphics performance General and 3D graphics capability .

Here is a general description of the experience you may encounter on a computer that receives the following basic indices :

  • A computer with a base index is 2.0 usually has sufficient performance for routine tasks such as running programs, business productivity and Internet research . However , a computer that has the base number is generally not powerful enough to run Aero or guarantee the advanced multimedia experiences that Windows 7 proposes .

  • A computer with the core index is 3.0 can run Aero and many features Windows 7 at a basic level . It is possible that some of the advanced features of Windows 7 are not fully available . Thus , a computer with the core index is 3.0 can display the theme Windows 7 by a resolution of 1280 × 1024, but may have trouble running this theme on multiple monitors . Similarly , it can play content from digital TV , but would have trouble reading the content of high definition television (HDTV).

  • A computer with the core index is 4.0 or 5.0 can run the new features Windows 7 and to support running multiple programs simultaneously.

  • A computer with a base index is 6.0 or 7.0 has a faster hard drive and can support graphical experiences of superior quality , such as a multiplayer game or 3D recording and playback HDTV content .

If a specific program or experience Windows 7 requires an index higher than your base number , you can put your hardware to achieve the required core index . If you install a new hardware and want to know if the index has changed , click Rerun evaluation. If you are prompted for an administrator password or confirmation , provide the password or confirmation .

The sub -indices correspond to the results of tests on the RAM , CPU , hard disk , graphics components of general office and 3D games on your computer . If your index is not sufficient basis for a program or a experience Windows 7Use sub-indexes to determine which components should be upgraded.

The base index is a good indicator of overall performance of your computer . The sub-indices may help to better understand the level of performance of your computer for specific experiences :

  1. Business productivity . If you use your computer primarily for business productivity experiences , such as word processing , spreadsheets , email and web browsing , sub -indices in the categories of high CPU and memory are essential. Sub -indices of 2.0 minimum is generally sufficient for the categories of widgets and desktop 3D graphics .

  2. Games and programs with intensive use of graphics. If you use your computer to play games or use programs to intensive use of graphics, such as digital video editing or games realistic first-person view , sub -indices higher in the categories of RAM, graphics components Office and graphic components for 3D games are essential . A sub-index of 3.0 minimum is usually sufficient in the category Hard Drive .

  3. Media Center experience . If you use your computer as a media center for multimedia experiences such as recording HDTV programs , high rates of sub- categories in the CPU , hard drive and desktop widgets are essential . Sub - indices of 3.0 minimum is generally sufficient in the categories of memory and 3D graphics components .

If you can not update the index base or sub-indices

The following conditions may prevent Windows update the performance index Windows :

  1. Battery operation .‌ Windows automatically tries to save energy when operating on battery only. If your computer is in this situation , an assessment of performance will not render account of its actual capabilities . Connect your computer and restart the sector assessment .

  2. Disk space. Assessment Tool Performance Index Windows creates a test file on your hard drive . If disk space is insufficient to create the test file , the evaluation can not be completed . Use the Disk Cleanup tool to free up space .

  3. The evaluation is already running . If the assessment tool Performance Index Windows is already running, your indexes may not be updated.

  4. The video driver is an older version . If your computer uses an earlier version of display driver, your clues will perhaps not be updated.

  5. No multimedia support . If your computer does not support multimedia , your indexes may not be updated .
