sudo apt-get purge linux-image-x.x-x-686-pae

Done, but sometimes you need to update grub with: sudo update-grub2

Possible solutions to disable missing comment warnings in Visual Studio:

• Suppress the warning by changing the project settings => Build tab => Errors and warnings => Suppress warnings by entering 1591
• Uncheck the "XML documentation file" checkbox in project settings => Build tab => Output
• Suppress the warning via compiler options, in beginning of file: #pragma warning disable 1591 and at end of file: #pragma warning restore 1591
• Use GhostDoc
• Add an empty comment :) ///<Summary></Summary>
