But the real kicker is this piece of advice: "Note The Secure Boot feature is supported in Windows 10. To learn more about the security advantages of this feature and about the upgrade path from Windows 7 to Windows 10, go to the following Windows website"
Holy toledo, this company really knows how to rub people up the wrong way.
