Um.. the information I need is what Input language to select in the Windows Control Panel. The Operating System is literally called "Windows" and it has settings for input language in its Control Panel. Nothing to do with your blackwidow model or the game's windowed mode.

There's no input language selection that says "English/Korean". There's an input language that says "Korean (Korea)" and under it there's dozens and dozens of Keyboard options, with the main one being simply "Korean". Is this the one I should be using in order to try to reproduce your issue?
Also, your window switching hotkeys are Ctrl+Alt+1 and Ctrl+Alt+2. This means that ISBoxer probably was unable to determine that you have an Alt Gr key on your keyboard, and at the end of the Quick Setup Wizard you didn't check the "I have an Alt Gr key" box. Make sure to do that next time, and the hotkeys will be shift+alt+1 and shift+alt+2 instead of using Ctrl+alt
