winsat.exeの実行

Windows エクスペリエンスインデックスを測定するためのexeは、winsat.exe (パス : C:\Windows\system32\WinSAT.exe)といいます。

これを管理者として実行することで、Windows エクスペリエンスが実行されます。*1

また、実行結果は%windir%\Performance\WinSAT\DataStoreにxmlで保存されます。

取得結果の閲覧

PowerShellでwmiあるいはcim経由で簡単に取得可能です。

Get-CimInstance Win32_WinSat

また、一度もエクスペリエンスを実行していなかったりした場合は、一度 winsat.exeを実行しておく必要があります。

Windows エクスペリエンスインデックスをPowerShellで実行する

以下のコマンドを管理者として起動したPowerShellで実行してください。

winsat formal -restart clean; Get-CimInstance Win32_WinSat

結果、Windows エクスペリエンスインデックスが表示されます。((管理者としてPowerShellを起動しなかった場合は全スコアが0になります。))

CPUScore              : 7.5
D3DScore              : 7.7
DiskScore             : 7.75
GraphicsScore         : 7.7
