How do I stop Windows OS from switching focus away from my keyboardtest program?

[DennisV]

Hello,
I am running KeyboardTest.exe. When the "Windows Logo" key is pressed, I lose the focus of my KeyboardTest program. In order for me to continue my test of other keys, I have to click on my KeyboardTest program. I would like to know how to keep the focus of my KeyboardTest program when the "Windows Logo" is pressed. Is there a way to tell KeyboardTest program to intercept the "Windows Logo" key, do the test, but do not pass the "Windows Logo" key code to the operating system.
Thank you for your help in advance,
Dennis

Select the 'Filter system keys' option and it should stay focused on the KeyboardTest program.

Hello Simon,
Thank you for your suggestion! It works for me. I have another question. How do I test the "Fn" key? What do I need to enter in my .kbl file?
Thanks,
Dennis

Hello Simon,
Please ignore my question on how to test the Fn key.
