Can't completely eliminate font smoothing in Window 10 with font substitution

Question

After my Win7 got broken recently I decided it is finally the time to upgrade to Win10. I (it seems like many others) hate blurry fonts configured in Win7+ and had clear-type and smoothing disabled in Win7. I'm trying to replicate the same in Win10, but can't make it work completely.

The result I have so far is on this picture ('OK' areas are green, 'bad' areas are red):

Steps i've done

• Uncheck : SystemPropertiesAdvanced.exe -> Performance -> Settings -> Smooth Edges of screen fonts
• Uncheck 'Turn on ClearType' in "Adjust ClearType text"
• Apply registry script to replace "Segoe UI" with "Tahoma" (because 'Segoe' without smoothig is extremly ugly)

The result I currently have is somewhat strange:

• In Google Chrome - everything is OK except hover-tooltips
• Windows Explorer is mostly OK except context menues
• Windows Taskbar - is all blurry :(
• Windows Task Manager - Titlebar, top menu and status line - OK, everything else is blurry

So it seems I'm missing some small thing, but can't catch it. Any ideas what is missing?

Note: At some early stage of experiments I had state when "Task bar" did use correct substituted fonts and without smoothing (as well as Task Manager was completely OK), but at the same time tabs in Google Chrome were blurry. Taskbar got borken while fixing Chrome - at that time i was experimenting with WinaeroTweaker application and I have no idea what it did to registry. Unfortuantelly i could not make Taskbar to be non-blurry again even after one-more fresh reinstall of Win10.

Registry script:

Answer 1

After digging more into this problem I've finally found the solution. There 2 problems:

1. Original 'reg' script I've took somewhere from internet had "MS Sans Serif" as target font. I've changed it Tahoma because "MS Sans Serif" seems to be too small.
2. It looks like different windows in MS applications have different font setting and therefore TrueType font are being smoothed in one places and not-smoothed in other places. Raster fonts (which "MS Sans Serif" is) are not smoothed in these 'wrong windows' when font-smoothing is not enabled.

Therefore solution will work only when substituting Segoe UI with some raster font. This however has adverse effect - large characters look ugly (what occurs rather rarelly and therefire is of less inconvinience to me than global blurriness):

Workable font-substitues are following:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]
"MS Shell Dlg 2"="MS Sans Serif"
"MS Shell Dlg"="MS Sans Serif"
"Segoe UI"="MS Sans Serif"
"Segoe UI Light"="MS Sans Serif"
"Segoe UI Semibold"="MS Sans Serif"
"Segoe UI Symbol"="MS Sans Serif"
"Segoe UI (TrueType)"="MS Sans Serif"
"Segoe UI Bold (TrueType)"="MS Sans Serif"
"Segoe UI Bold Italic (TrueType)"="MS Sans Serif"
"Segoe UI Italic (TrueType)"="MS Sans Serif"

Answer 2

Make sure you have the windows update component enabled. Go to Start > Settings (or PC settings if you use Classic shell) > Apps & features > Manage Optional Features, hit Add a feature > download the "Korean supplemental Fonts" once that has finished, run the registry files that's been provided, except replace "MS Sans Serif" with "Dotum"

The Dotum font is not a raster font (also known as a bitmap font) and is the closest I've found to Tahoma. I really hope someone finds a better solution or font because aliased fonts are bad for your eyes long term.
