Weird fonts in Windows 10 after upgrading from 7

Hello,

I recently upgraded my Windows from 7 to 10 and noticed that some of the fonts were really weird. Chromes tab titles are using weird font and when I searched a bit, it seems that it uses Windows' "Message box" fonts. Other applications for example are Steam(I was able to fix this via creating new simple theme).

It also seems to be problem ONLY in my main Windows user account. Most likely my Windows 7 custom theme did this and now those changes are still in effect.

So my question is: Where are these changes located in Windows 10? How do I reset or change them? In Windows 7 there was a way to change font type in title bar, menu, message box etc but I have no idea how to do this in 10.

Thank you in advance.

In the advanced display settings, you can change the size and boldness of the fonts, but not the font itself. I'm still trying to figure out how to get the system fonts properly changed. Also, even with resizing and bolding the fonts, it seems Windows 10 resets them on me frequently, especially after it installs updates. It's driving me crazy. I had custom fonts with Win 8.1 before this and I did it with hacking the registry, but I heard Windows 10 ignores the entries if you try it now.

Registry hack still works fine.
