Uninstalling a Font Using the Fonts Folder

Open the Fonts folder located at C:\Windows\Fonts

uninstall a font using registry

Right-click the font you want to remove, and click Delete

Uninstalling a Font Manually Using Regedit

There are chances that the Fonts folder doesn’t show the font you installed. In that case you need to edit the registry to remove it.

Let’s assume you installed the 3rd party HelveticaNeue font and want to uninstall it. Use the following instructions.

1. Start Regedit.exe and go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts

2. Backup the branch by exporting to a .REG file.

3. In the right-pane, delete the following values:



  • HelveticaNeue-UltraLigCond (TrueType)
  • HelveticaNeue-UltraLigCondObl (TrueType)
  • HelveticaNeue-UltraLigExt (TrueType)
  • HelveticaNeue-UltraLigExtObl (TrueType)
  • HelveticaNeue-UltraLight (TrueType)
  • HelveticaNeue-UltraLightItal (TrueType)

4. Exit the Registry Editor.

5. Logoff and login back so that the fonts are no longer in use by the system.

6. Then manually delete following .otf files from C:\Windows\Fonts using Command Prompt (Admin).

  • HelveticaNeue-UltraLigCond_0.otf
  • HelveticaNeue-UltraLigCondObl.otf
  • HelveticaNeue-UltraLigExt.otf
  • HelveticaNeue-UltraLigExtObl.otf
  • HelveticaNeue-UltraLight.otf
  • HelveticaNeue-UltraLightItal.otf

7. Running this command will show the list of .otf files you installed.

dir c:\windows\fonts\helvetica*.otf

(There zip file in the above website bundles 6 .otf files, which you need to delete from the Fonts folder.)

8. Then run:

del c:\windows\fonts\helvetica*.otf

Note: Font file extensions can be one of these:

.FON | .OTF | .TTC | .TTF

That’s it! The above is just an example, taking the case of HelveticaNeue font. However, the same procedure can be applied to uninstall any third-party font.

  1. I copied and pasted the fix for Win10, saved it as segoe.reg When I double click the saved file it tells me that it is not a registry script file. When I go into regedit and try to import it, it tells me that it is not a registry file. What did I miss?

  2. OMG I screwed up the font settings and I almost did a system reset to fix it after a whole day of searching for registry backups online was futile, and then I somehow got here! I copy-pasted the default settings, created the file and fixed it, easy peasy 😀
