Weird fonts issue in one application since 1703

[nid]

I will try to keep this as short as possible.

There is a specific app I use in two different PCs and ever after 1703 got installed I've had an issue where the main font of the app gets changed and looks very hard to read. The best clue is the following: with every new major windows build update, on the first boot after the update the font is the correct one as it is in all other healthy computers. But after the first restart (or logout and login again), it reverts to a different small and blurry font. So something is stuck in there and keeps messing the fonts.

I formatted computer #1 and reinstalled windows and the issue went away. So far that's the ONLY way I've found to deal with this persistent "illness". It also proves it's not hardware related. On computer #2 (which is the one I can't afford to format, hence I'm requesting help!) the issue still remains, even after the latest 1803 update. I also tried the "in-place upgrade" "windows 10 refresh" trick, which worked fine but again after the first Windows restart, again the same issue. I'm now positive that what is going on is that the app in question is being blocked access to a specific font that it was designed to work with and it reverts to another font which looks like "small and blurry". So I think it's not a font size changing issue but that it switches to a totally different (and inappropriate) font. Something probably in the registry is stuck and keeps doing something with the system fonts no matter if a whole Windows build update takes place! It's also not a scaling issue, please don't waste time looking at scaling issues. It is a font system issue.

I've tried tons of things to no avail. Any ideas would be greatly appreciated.

This is defiantly a font issue. 

Have you tried to reset font settings to default?

Thanks! Your script didn't help as it is but gave me another idea as a workaround. I deleted all the entries of [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] and that fixed it! I know it is not the most elegant way but it works. After that the app in question does not use a substitute as it was doing before and uses the correct font instead. The entries were the same as in another machine that was "healthy" so the issue is not exactly this but something else that triggers this font substitution to take place on the "ill" machine. I don't know what that is or whether I'm ever going to find out. For now case is solved, even by this workaround.
