Windows System Assessment Tool（WinSAT）是Windows操作系统中的一个工具，用于评估和测量计算机硬件的性能。通过运行不同的评估，WinSAT可以生成关于CPU、内存、硬盘、图形等方面性能的指标和分数，帮助用户了解其计算机的整体性能水平。

COMMAND LINE USAGE : WINSAT [switches]

It's necessary to supply an assessment name. In contrast, switches are optional.Valid assessment names already seen in Vista include:

formal run the full set of assessments

dwm Run the Desktop Windows Manager assessment - Re-assess the systems graphics capabilities and restart the Desktop Window Manager.

cpu Run the CPU assessment. mem Run the system memory assessment. d3d Run the d3d assessment (Note that the d3d assessment no longer runs the workload. For backward compatibility, pre-determined scores and metrics are reported.) disk Run the storage assessment media Run the media assessment mfmedia Run the Media Foundation based assessment features Run just the features assessment - Enumerates the system's features. - It's best used with the -xml switch to save the data. - The 'eef'switch can be used to enumerate extra features such as optical disks, memory modules, and other items.

PRE-POPULATION:The new command-line options for pre-populating WinSAT assessment results are :

Winsat prepop [-datastore ] [ -graphics | -cpu | -mem | -disk | -dwm ]

This generates WinSAT xml files whose filenames contain "prepop". For example : 0008-09-26 14.48.28.542 Cpu.Assessment (Prepop).WinSAT.xml

The filename pattern is : %IdentifierDerivedFromDate% %Component%.Assessment(Prepop).WinSAT.xml

The datastore directory option specifies an alternative target location for generated xml files.If no location is specified, everything is pre-populated to %WINDIR%\performance\winsat\datastore.

To generate a full set of result xml files, use "winsat prepop".

It is also possible to pre-populate results for a subsystem, such as CPU,subject to the following dependencies:

The CPU assessment has a secondary dependency on the Memory assessment The Memory assessment has a secondary dependency on the CPU assessment The Graphics assessment has a secondary dependency on both CPU and Memory assessments The DWM assessment can run standalone The Disk assessment can run standalone

If the assessment for a secondary dependency is not present, WinSAT will run thesecondary assessment along with the requested primary assessment.

For example, "winsat prepop -cpu" will run both the CPU and the Memory test,if the xml file for the Memory test is not present.

OTHER NEW Win7 ASSESSMENT OPTIONS :

dwmformal Run Desktop Windows Manager assessment to generate the WinSAT Graphics score cpuformal Run CPU assessment to generate the WinSAT Processor score memformal Run Memory assessment to generate the WinSAT Memory (RAM) score graphicsformal Run Graphics assessment to generate the WinSAT Gaming Graphics score diskformal Run Disk assessment to generate the WinSAT Primary Hard Disk score

All formal assessments will save the data (xml files) in %WINDIR%\performance\winsat\datastore.

If a system has been prepopulated (using files generated by the "winsat prepop" option),it is not necessary to run formal assessments.

SUB-ASSESSMENTS:While investigating results, it may be convenient to look at individual assessments.Options for running Gaming Graphics sub-assessments include:

DX9 Variations: Winsat d3d -dx9 winsat d3d -batch winsat d3d -alpha winsat d3d -tex winsat d3d -alu

DWM/DX10 variations: Winsat d3d -dx10 winsat d3d -dx10 -alpha winsat d3d -dx10 -tex winsat d3d -dx10 -alu winsat d3d -dx10 -batch winsat d3d -dx10 -geomf4 winsat d3d -dx10 -geomf27 winsat d3d -dx10 -geomv8 winsat d3d -dx10 -gemov32 winsat d3d -dx10 -cbuffer

OPTIONS FOR FORMAL ASSESSMENTS FOR SUBSEQUENT RUNS ON THE SAME MACHINE:

The default behavior for "WinSAT formal" when a complete set of winsat formal files is presentand a second "winsat formal" run is requested is to 1) Run incrementally if component change implies that an assessment needs to be re-run, e.g. if a video card were updated 2) If no component updates were detected, re-run all assessments.

The restart option enables behavior other than the default. The syntax is : Winsat formal -restart [clean|never]

Winsat formal -restart Reruns all assessments. Winsat formal -restart never Attempts to run incrementally. Winsat formal -restart clean Reruns all assessments and provides the same functionality as "forgethistory". Winsat forgethistory Choosing to forgethistory will rate a machine as if for the first time.

OTHER COMMAND LINE OPTIONS : -v Enables verbose output -xml Saves the XML output to 'filename'

-log Generates a log file associated with the specified command, such as disk The -log switch can be used with any WinSAT command.

viewlog -i Dumps the results of a log file . viewevents Used to view relevant winsat events in the event log. (This launches the event log) query Can be used to query the current datastore.
