Using WinSAT, you can measure the following components of your Windows computer:
CPUMemoryDirect3D assessmentVideo card/Gaming graphics/Media/Media Foundation assessmentPrimary disk or storageFeatures.
To use the Windows System Assessment Tool, open an elevated command prompt, type winsat /? and hit Enter. This will display Help and show you all the arguments, switches and options available.
Here is a list of syntax and assessments available. For more information, you can visit TechNet. In Windows 8/7/Vista, the Windows System Assessment Tool is also used in calculating the Windows Experience Index. Although the command line winsat or Windows System Assessment Tool still exists in Windows 10/8.1, the Windows Experience Index score is not displayed. But there is a workaround for this too. BONUS TIP: Consider it an Easter Egg, if you wish! Windows Vista introduced an inbuilt 3D Benchmark, in the Windows System Assessment Tool. This tool benchmarks your Computer during installation. But if you want to run this benchmark, anytime, you can do so from the command line by using winsat along with command line parameters.
Windows System Assessment Tool has stopped working
If WinSAT or Windows System Assessment Tool has stopped working on your Windows, run the system file checker sfc /scannow and see if it helps. You could also boot in Safe Mode or Clean Boot State and see if it works, when in this state. Hope you find the post useful.
