I'm new to Windows Blinds so if this has been discussed, please just point me to the relevant post. As I'm getting older, the default fonts in several places in Windows are getting too small (notably the filenames in the Open Save File dialogs). I found out that It's very hard to change only some specific fonts, without messing up the entire Windows look. I have utilities like WinAero Tweaker and WinTools . They let me change some fonts, but this inevitably leads to some unwanted font changes in some places I didn't expect. I also know of the Windows "DPI setting. I tried 135%, but, in my case, it doesn't affect some the fonts in the filename edit boxes in Save / Open File dialogs. My latest attempt is to try to use Windows to take the default Windows theme and "surgically" modify it in just a few selected aspects (e.g. the Save / Open File dialogs). After installing WindowBlinds I've noticed that the "Default" Windows theme cannot be edited via right-click on theme preview, "Edit". I assume it's so that the user doesn't mess up the default theme without a way of recovering from it. What could work is making a 1:1 copy of the default Win10 theme and package it as a separate theme, which then can be edited, without changing the original Windows files. Has someone made a 1:1 copy of the default Windows theme that I an edit?
