Disabling language changes in Visual Studio

On a recent project I used a workstation given to me by the client. It was typical "big enterprise" setup with support for multiple languages. I discovered there's a keyboard shortcut "Ctrl+Space" for changing your language that I would keep accidentally activating in Visual Studio. This protip explains how to disable that.

Go to the control panel.
Choose "Region and Language".
Click the "Keyboard and Layout" tab.
Click on "Change Keyboards".
Click on "Advanced Key Settings".
Look over the list of sequences, ensure they are all set to "none" for keyboard activation.
