Such programs are super annoying. I had this problem on my computer - some program is occasionally stealing window focus, resulting in being switched out of full-screen games at inopportune times etc..

So I made a program to detect such annoying programs - https://github.com/glaretechnologies/focusmonitor.

I figured out the offending program is C:\Users\nick\AppData\Local\Akamai\installer_no_upload_silent.exe.

Dear Akamai: please fix your annoying program to not steal window focus. Thank you.

I have looked at this program that presumably does the same thing: http://www.happydroid.com/focus, but Windows Defender said it had a virus in it. Not sure if that is true, but I'm hesitant to run unsigned executables from random sources anyway. So I made my own.
