Typography.Capitals not working on Windows 7

Question

For example in the following label I want to use SmallCaps, but they only show up on Windows 8 and higher. On Windows 7, there are just normal letters.

<Label x:Name="servername" Typography.Capitals="SmallCaps" Content="Server xy" VerticalAlignment="Bottom" FontSize="15" Margin="10,0,10,31" Padding="5,0"  FontWeight="Light" Height="19" HorizontalAlignment="Left" SizeChanged="servername_SizeChanged"/>

I'm using .NET Framework 4.5 and the font is Segoe UI Medium (and in some other labels Segoe UI Light), which is installed on both systems.

As you may know, Typography.Capitals support is provided by the OpenType font family itself: https://msdn.microsoft.com/en-us/library/system.windows.documents.typography.capitals(v=vs.110).aspx

OpenType supports a number of styling formats for capitals, including small capitals, petite capitals, titling, and capital spacing. These styling formats allow you to control the appearance of capitals.

Small caps support for Segoe UI was added for Windows 8. The Windows 7 version of Segoe UI does not support small caps.

The new Segoe UI also adds support for OpenType stylistic sets and ligatures which increases variation across the standard character set. New features include small caps, old-style and tabular (monospaced) numerals. In fact, the old variations of the characters above are included in the alternative style set (style set #20, in fact).

I'm unsure of the possibility and legality of packaging up the updated version of Segoe UI for use in your own WPF application.
