Windows System Assessment Tool

The Windows Experience Index (English: Windows Experience Index ( WEI) ) is a module of Windows Vista, 7, and 8, which provides information about the performance of individual components and the overall system of a personal computer using a numerical scale.

The function can have a simultaneous pressure on both the Windows and Pause buttons or via the Control Panel, under "Performance Information and Tools " are called and to give the user the ability to easily control whether software, noted their performance numbers on the packaging is running on the system. In addition, to be so easily recognizable, in which hardware component upgrades that makes sense. In Windows 8.1, the performance index no longer be calculated or displayed through the user interface, but winsat only via the command line utility. However, there is now a tool called HWinSAT.exe with which even in Windows 8.1, the performance index in the usual form (including history ) to provide details. Programs place on the basis of the available evaluation scope determines output warning signals or deny the installation, so there are also programs to the index to manipulate.

Construction

The index shows the performance of the individual computer components such as processor, memory, graphics card and hard drive, and can for example be updates of the operating system also depends on the installed software. The results of the test are displayed as numerical values. In Microsoft Windows Vista, the performance scale of 1.0 (lowest value, low performance) to 5.9 (maximum score high power), Microsoft Windows 7 1.0 to 7.9 and in Microsoft Windows 8 is 1, 0 to 9.9. The overall computer performance results from the lowest subscore. Particularly low results may point to outdated hardware or computer problems (such as faulty hardware or missing / wrong device driver ).

To achieve 7.9 on Windows 7 Microsoft has identified the following components:

  • Desktop processor with four cores and at least 4 GHz ( with water cooling for overclocking ) or processor with six cores
  • Socket 1366 Motherboard
  • Desktop storage system with low power consumption and 12 GB RAM
  • GTX 285 graphics card
  • Internal SSD with 256 GB in striped RAID 0 configuration
  • 1,000 - watt power supply
