Went to the tutorial you mentioned.....
This will show you how to change most or all of the default fonts in Windows 7 for Active Title Bar, Icon, Inactive Title Bar, Menu, Message Box, Palette Title, Selected Items, ToolTip, and various Dialog Box text and buttons.
Changing a Windows 7 font doesn't change your program fonts.
You will see, that the very "explicit" question I asked, was if there was a way to change "program fonts", which this tutorial "explicitly" advises does not do.
I assume that I will have to change my display to 125% or 150%, as I did mention, however I was just looking to see if there was a "quick" way to increase program fonts, without having to re-login each time.....
