I'm testing a Windows application for usability. While I thought the application looked pretty usable at first, I tried the application using the "Large text" setting in Windows 7 and realised that some text containers were now too small to accommodate for the large text.
While the idea of changing the text size occurred to me by chance, I'm now thinking that there may be a panoply of other Windows settings that I should change and test for.
What are the common Windows 7 settings I need to test to make sure my application is universally usable?
