Bold Font Rendering Issue After Replacing Segoe UI with SF Pro Text via Registry Edit in Windows 11

Description:

After changing the system font in Windows 11 by replacing Segoe UI with SF Pro Text via registry settings, I encountered an issue with bold font rendering. Noticed it, I've tried mapping Segoe UI Bold (TrueType) font to SF Pro Text Bold in registry editor, but bold text still appears strange or incorrectly rendered in applications like Google Chrome. Despite installing all necessary SF Pro Text font files and modifying the registry, the issue persists, and Chrome continues to display bold text inconsistently.

The problem is same as this question https://answers.microsoft.com/en-us/windows/forum/all/the-bold-font-too-thick-after-changing-the-system/83922195-63d7-4782-b9be-7df475ad38c7. But I didn't find any useful solution in it.

Steps I took:

1. Installed SF Pro Text fonts, including bold variants. I installed all fonts from https://github.com/sahibjotsaggu/San-Francisco-Pro-Fonts.
2. I initially replaced Segoe UI with SF Pro Text in Windows 11 by modifying the registry. The first file I merged was:

   
       Windows Registry Editor Version 5.00 
   
       [HKEY\_LOCAL\_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] 
   
       "Segoe UI (TrueType)"="" 
   
       "Segoe UI Bold (TrueType)"="" 
   
       "Segoe UI Bold Italic (TrueType)"="" 
   
       "Segoe UI Italic (TrueType)"="" 
   
       "Segoe UI Light (TrueType)"="" 
   
       "Segoe UI Semibold (TrueType)"="" 
   
       "Segoe UI Symbol (TrueType)"="" 
   
       [HKEY\_LOCAL\_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] 
   
       "Segoe UI"="SF Pro Text" 
   
   

3. Restarting and the issues occur. After noticing issues with bold font rendering, I further updated the registry to link specific SF Pro Text fonts to the corresponding Segoe UI fonts:

   
       Windows Registry Editor Version 5.00 
   
       [HKEY\_LOCAL\_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] 
   
       "Segoe UI (TrueType)"="SF-Pro-Text-Regular.otf" 
   
       "Segoe UI Bold (TrueType)"="SF-Pro-Text-Bold.otf" 
   
       "Segoe UI Bold Italic (TrueType)"="SF-Pro-Text-BoldItalic.otf" 
   
       "Segoe UI Italic (TrueType)"="SF-Pro-Text-MediumItalic.otf" 
   
       "Segoe UI Light (TrueType)"="SF-Pro-Text-Light.otf" 
   
       "Segoe UI Semibold (TrueType)"="SF-Pro-Text-Semibold.otf" 
   
       "Segoe UI Symbol (TrueType)"="" 
   
       [HKEY\_LOCAL\_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] 
   
       "Segoe UI"="SF Pro Text" 
   
   

4. I merged the .reg file and restart. Despite these changes, bold text still appears strange or incorrectly rendered in certain applications, including Chrome. The issue persists even after restarting the system.

Expected Behavior: The system should render bold text using SF Pro Text Bold without any issues.

Actual Behavior: Bold text is still rendered incorrectly, causing a strange appearance in certain applications, including Chrome.
