A. You can run WinSAT from the command line and tell it to run the full suite of tests to generate scores or test just individual elements, for example "winsat formal" runs all the tests for performance testing and then updates the scores of the system by writing the data to the %systemroot%\Windows\Performance\WinSAT\DataStore. To view the features of the system, use the "winsat features" command, as the following example and resulting output show:

 

 C:\Windows\system32>winsat features

You can also run individual tests for the following elements:
- cpu - runs the cpu assessment

- mem - runs the system memory assessment

- dwm - runs the desktop window manager assessment

- d3d - runs the d3d assessment

- media - runs the media assessment

- mfmedia - runs the Media Foundation-based assessment

- disk - runs the storage assessment

Each test might then have other parameters. For example, to test the CPU, you can run an encryption or compression test. The following command runs a CPU compression test:

 

 C:\Windows\system32>winsat cpu -compression  

Which produces this output:
Windows System Assessment Tool

> Running: Feature Enumeration v1.0.0.0 '
> Run Time 00:00:00.56

> Running: CPU Assessment v1.0.0.0 '-compression'

> Run Time 00:00:10.45

> CPU LZW Compression 87.98 MB/s

> Total Run Time 00:00:12.47

Additional switches you can use with the winsat command include the verbose switch (-v) and the XML output file (-xml ).
