The DHS Trusted Tester course includes using the Microsoft Inspect tool.
To obtain this tool, you need to extract the tool from the .NET Framework 4 (ISO).
I found an excellent step-by-step solution on Stack Overflow.

Download the Microsoft Windows SDK for Windows 7 and .NET Framework 4 (ISO)
Unzip using 7Zip
Navigate to, Setup\WinSDKTools
Open, cab1.cab (this is just like a .zip file, any archive tool should be able to open it)
Extract WinSDK_Inspect_exe_x86 to a folder on your computer
Add the .exe extension
I should mention that Window Detective does the same thing as Inspect.exe, but does it better, so it's an excellent alternative.
