What is the Windows Experience Index?


The Windows Experience Index is a measurement that tells you how well your PC works with Windows and uses a base score to rate the experience you can expect. A higher base score usually means that your PC will be faster and more responsive than a PC with a lower base score.

Each piece of hardware in your PC gets its own score called a subscore. The total base score for your PC is determined by the lowest individual subscore, rather than an average of them all. You can view the subscores to see how the hardware you care most about is performing, which can help your decide whether to upgrade some parts of your PC.

To view your PC's base score

  1. Open Performance Information and Tools by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Performance Information and Tools in the search box, tapping or clicking Settings, and then tapping or clicking Performance Information and Tools.

  2. View the Windows Experience Index base score and subscores for your computer. If you recently upgraded your hardware and want to find out if your score has changed, tap or click Re-run the assessment. Administrator permission required You might be asked for an admin password or to confirm your choice.

    If you don't see subscores and a base score, tap or click Rate this computer. Administrator permission required You might be asked for an admin password or to confirm your choice.

Note

  • The Windows Experience Index base score typically ranges from 1.0 to 7.9. However, if your PC has a 64-bit processor and 4 GB or less random access memory (RAM), then the Memory (RAM) subscore for your PC will have a maximum of 5.9. This means that the overall base score will also be limited to 5.9.

If your base score or subscores can't be updated

The following conditions might prevent Windows from updating the Windows Experience Index:

  • Running on battery power.‌ Windows automatically tries to conserve power when running on a battery alone. So if your PC is running on battery power, a performance assessment won't reflect its true capabilities. Plug your PC in, and then re-run the assessment.

  • Not enough free drive space. When you assess your PC, the Windows Experience Index creates a test file on your hard drive. If there's not enough free space to create the test file, the assessment can't be completed. You can use the Disk Cleanup tool to free up space. For more info, see Delete files using Disk Cleanup.

  • The assessment is already running. If you're already running a Windows Experience Index assessment, your scores can't be updated.

  • The video driver is older. If your PC is using an older version of the video driver, your scores might not be updated.

  • No multimedia support. If your PC doesn't have multimedia support, your scores can't be updated.
