How can I fix font bugs in Windows 10?

2. Find Language option and check what language is set as default.
3. If you want to set a different language, you can change it by clicking Add a language option.
   
4. Choose your preferred language and click Set as default.

This isn’t the best solution, but it might help if English is not set as your predefined language, so it’s worth checking out.

2. Reinstall the font

If you have upgraded to Windows 10 from Windows 7, it might happen that your font wasn’t installed properly so you need to reinstall it manually.

If this sounds complicated, don’t worry, it’s simpler than it sounds. To do this:

1. Go to C:WindowsFonts if you did a clean install of Windows 10. If you have upgraded from Windows 7 or Windows 8 you need to go to C:Windows.oldWindowsFonts.
2. Now you need to find the font that is giving you trouble. In most cases, it’s Arial or Mingliu. Find the font file and open it to preview the font.
   
3. In the preview window click Install on the top right corner and you’ll reinstall the font manually.
   
4. If for some reason these fonts are missing you can always download or copy them from another PC.

You can also install the missing font using the Command Prompt. This method is intended for advanced users, but it’s also faster than the previous method. To install the missing font, just do the following:

1. Press Windows Key + X to open Win + X menu. Now select Command Prompt (Admin) from the list. If the Command Prompt isn’t available, you can also use PowerShell (Admin).
2. When Command Prompt opens, enter C:WindowsFontsArial.ttf and press Enter.
   
3. The font preview window will now appear. Click on the Install button to install the font.

Keep in mind that you need to repeat these methods for all missing fonts.

As you can see, this method is useful if you’re missing just one or two fonts, but if you’re missing more fonts, you might want to try a different method.

3. Disable scaling on high DPI settings

Sometimes, font bugs are caused by high DPI displays, so the solution is to disable high DPI settings. Do the following:

1. Right-click the executable file that has font bugs. Select Properties from the context menu.
   
2. Then go to the Compatibility tab. Disable Display scaling on high DPI settings and click Apply and OK to save changes.
   

Save the changes and restart your application to see if the problems were fixed.

We have to warn you that this solution might cause your fonts in the application to be smaller, so you might have to adjust their size manually.

Also, if several applications are giving you problems, you need to repeat this step for each one of them.

4. Modify your registry

If you’re having font bugs on Windows 10, the issue might be caused by your registry. Sometimes certain problems can appear if your registry values aren’t correct, and in order to fix that, you need to change them manually.

To do that, follow these steps:

1. Press Windows Key + R and enter regedit. Press Enter or click OK.
   
2. Optional: Modifying the registry is potentially dangerous, so in order to avoid any future problems, it’s advised to export your registry and create a backup. To do that, just click on File > Export.
   Set Export range as All and enter the desired file name. Choose a save location and click on Save.
   After doing that, you’ll have a backup of your registry. If anything goes wrong after making the changes, simply run the exported file to restore your registry to the original state.
3. In the left pane, navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionGRE_Initialize and double click DisableFontBootCache in the left pane.
   
4. Set Value data to 1 and click on OK to save changes.
   
5. Close Registry Editor and restart your PC.

After doing that, the problem with fonts should be completely resolved. It’s worth mentioning that using this method might cause a slower boot, so don’t be surprised if your PC is booting slower than usual.

5. Remove the problematic update

If you’re having font bugs on your PC, the problem might be related to a specific update. Sometimes an update can cause this problem to appear, and the only way to fix it is to find and remove the problematic update.

This is relatively simple, and you can do it by following these steps:

1. Open the Settings app and navigate to Update & Security.
   
2. Now choose View installed update history from the menu on the right.
   
3. Select Uninstall updates.

Once you remove the update, check whether the issue is still there. It’s worth mentioning that Windows 10 will automatically install the missing updates causing the problem to reoccur.

To do that, just go to C:WindowsSystem32 directory and locate FNTCACHE.DAT. Delete that file, and restart your PC and the problem should be resolved.

Keep in mind that this is just a workaround, so you’ll need to repeat it every time before you turn off or restart your PC.

8. Rebuild the font cache

Sometimes, font bugs can appear due to font cache corruption. To fix that, you need to delete temporary files in order to rebuild your cache. This is rather simple and you can do it by following these steps:

1. Press Windows Key + R and enter services.msc. Now press Enter or click OK.
   
2. When the Services window opens, locate Windows Presentation Foundation Font Cache 3.0.0.0 service and stop it. To do that quickly, just right-click the service and choose Stop from the menu. If the service is already stopped, move to the next step.
   
3. Press Windows Key + R and enter %windir%ServiceProfilesLocalServiceAppData. Press Enter or click OK. If you get a warning dialog, just click on Continue.
   
4. Navigate to the Local directory. Now locate any files that have ~FontCache- prefix and delete them. If you can find any of these files in the Local directory, go to the FontCache directory. Now delete all files with ~FontCache- prefix.
