I'm all for more people switching to linux, but a lot of your windows issues sound less like windows issues and more like your specific installation is messed up somehow issues.
One thing I will mention though is that Windows does have native per-application volume control, you don't need to install EarTrumpet. You can right-click the system tray volume icon and open the mixer, or just search for "volume mixer" in the start menu.
To be fair his prior rant was about how bad he was at using and understanding Linux.
