1. Open a new file for editing on the Notepad.
   
2. Enter the following code as and it is.

   Windows Registry Editor Version 5.00
   
   [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]

   "Segoe UI"=-

   

3. Click on File and from the menu select Save As. Otherwise, you may press Ctrl + Shift + S to save the file.
4. Set a file name but use the .reg filename extension(for example, abc.reg) and change Save As Type to All Files.
5. Once done, click on Save.
6. Now, go to the location where you saved the registry file.
7. Right-click on the file and select Open.
8. A prompt will show up, and you have to confirm opening this registry file. Click on Yes.

Note that, in the above two methods, when you create a new registry file, you are modifying the existing registry of Windows. Carefully, copy the code fragments and make sure not to alter them in any way. Doing so may cause Windows OS to behave erratically. As the methods involve tweaking the registry, do so at your risk.
