Asking for Help on Customizing Font

Hello all! I have no technical knowledge of computer. On XP, as far as I can remember, I edited a file, which I now can't remember, in the program "Restorator" and changed the font size as befitted my needs. In Windows 7, I think I had no serious problem concerning the size of the font. Unfortunately, in Windows 10 I've had to do a lot of more customization than the previous versions with no success in changing the font size.

I've read perhaps all that has been posted here and elsewhere and have tried Winaero Tweaker,[1] changesize, and advchange[2] as well with no desirable result. Your suggestions and these programs only help to increase the font size ignoring the suitable lines-distance required. Please help me through kindly telling which resource file(s) on Windows 10 should be hacked in this regard or if there already exists a designed theme with bigger font size. Thanks past measure.

As you see in the following, the font size is increased with no proportion with the distance between the lines (the characters "g" and "p", for instance, are not wholly visible due to improper vertical space between the font characters):

[1] Winaero - Free small and useful software for Windows
[2] System Font Size Changer - WinTools.Info

As you see in the following,

There in nothing after the colon, no example showing.

Referring to my previous thread which I thought was solved (Asking for Help on Customizing Font Solved - Windows 10 Forums), I should point out that custom scaling in Display Settings is still incompatible with some applications and does not do. The problem still needs consideration and should be solved in a way. I wonder why Win 98 was much more flawless and customizable than the later versions of MS Windows!!!! The pictures below show nCleaner's main screen before and after the change of scaling. The pic above is related to the time after custom scaling and the pic at bottom to the stage before scaling. To exit nCleaner after custom scaling, we should click somewhere outside the program's screen instead of clicking the Close button!!! :)
