Unfortunately, and the specifics here may vary some for different users depending on monitor configuration, while this guidance to select "System (Enhanced)" improves the main terminal window, it makes the home "PuTTY Configuration" window worse or has no effect. For that, I need to change to instead select the high DPI scaling override option of "Application." This suggests that PuTTY uses different rendering systems for the two windows. There is no way to select different high DPI scaling options for different windows, meaning whatever option fixes one can make the other worse. Because the terminal emulation window is the more important, I stick with "System (Enhanced)" scaling, but this results in a blurry PuTTY Configuration main window.

This should be corrected by PuTTY developers to ensure both windows use the same rendering system, regardless of which -- just make them the same so that users can then select the high DPI scaling override that works best for that user (on ALL PuTTY windows).
