Since Windows Vista, including in Windows 7, Windows Server 2008 and Windows Server 2008 R2, Windows System Assessment Tool (WinSAT) has been added into the operating system. WinSAT is a free benchmarking tool that measures various computer performance ratings, characteristics and capabilities, and display the ratings as Windows Experience Index or WEI score.
Normally, WEI rating score is just a few generalized numbers (which can be manipulated) of a relative performance scale, which do not give in-depth details about the computer performance. For advanced users who want to know the very details performance ratings for each components measured by WinSAT, there is trick to display detailed performance rating scores.
To view the PC performance details with WinSAT, open Command Prompt window as administrator, and enter the following command:
winsat formal -v >> output.txt
What the command does is it will run formal assessment on all system devices or sub-components to calculate the performance benchmarks, which is also used to calculate Windows Experience Index. All performance ratings will be saved and recorded in output.txt in the current directory. Unlike WEI, the content in the output file is comprehensive and detailed.
