Today I fired up a copy of Microsoft Works 4.5 on Windows 98, and realised that I still don't know how they styled the window title bar to have Microsoft in italics, and a gradient colour. The gradient is not from the theme, as it displays like this on Windows 95 as well (which does not support the native gradient styling like Windows 98).
Below are two screenshots showing this in action in two different themes:
Does anyone know how Microsoft achieved this, or if there is any old sample code on how to achieve this on older versions of Windows?
