Results for the WinSAT Comprehensive Assessment
Applies To: Windows 8
The WinSAT Comprehensive assessment runs the WinSAT.EXE program and generates engineering metrics that lead to the Windows Experience Index (WinEI). WinEI is a set of scores that enables you to compare hardware on different computers. Although this assessment does calculate the scores, its primary purpose is to provide access to the underlying metrics related to the scores.

Goals File
You can create custom goals to measure your improvements in the Results View. Goals files are a triage tool that can help you understand how a PC is performing and to compare PCs in your business.
For example, goals for a basic laptop might be different than the goals you set for a high end desktop computer, or market expectations might change in such a way that you want the flexibility to define different goals and key requirements as time passes and technology improves.
When a metric value is compared to the goal for that metric, the status is color coded in the Result View as follows:
Light purple means that the system has a great user experience and that there are no perceived problems.
Medium purple means that the user experience is tolerable and you can optimize the system. Review the recommendations and analysis to see what improvements can be made to the system. These can be software changes, configuration changes or hardware changes.
Dark purple means that the system has a poor user experience and that there is significant room for improvements. Review the recommendations and analysis to see the improvements that can be made to the system. These can be software changes, configuration changes or hardware changes. You might have to consider making tradeoffs to deliver a high quality Windows experience.
No color means that there are no goals defined for the metric.
Note
In the Windows Assessment Toolkit for Windows 8, some assessments include default goals files. The first time you view results using this version of the tools, the default goals file is used. However, you can also define custom goals for Windows 8 the same way that you can for Windows 8.1.
You can set the goals file location and add a goals file to that location before you can use the UI to apply the custom goals. Once a goals file is selected it will continue to be the goals file that is used for any results that are opened.
Only one goals file can be used at a time. Goals for all assessments are set in a single goals file. The assessment tools will search for goals in the following order:
A custom goals file
Goals that are defined in the results file
Goals that are defined in the assessment manifest
You can use the sample goals file that is provided at %PROGRAMFILES%\Windows Kits\8.1\Assessment and Deployment Kit\Windows Assessment Toolkit\SDK\Samples\Goals to create your own goals file.
Note
You cannot package a goals file with a job, but you can store it on a share for others to use.

Issues
Because the WinSAT assessment provides only metrics that are derived from the WinSAT Formal pre-defined set of assessments, and because these values are so different from one system configuration to another, specific issues and recommendations are not provided for this assessment. For more information about WinSAT Formal, see WinSAT Formal.
For additional information about WinSAT components, see WinSAT.
The assessment reports an exit code of 0x80050006
This error occurs when maintenance tasks have been registered on the PC but have not completed before the assessment run. This prevents the assessment from running, as maintenance tasks often impact assessment metrics.
To resolve this issue, do one of the following:
Ensure that the computer is connected to a network and is running on AC power. Manually initiate pending maintenance tasks with the following command from an elevated prompt:
rundll32.exe advapi32.dll,ProcessIdleTasksDisable regular and idle maintenance tasks, and stop all maintenance tasks before running the assessment.
