[Sobre o Windows 10] How to change system font in Windows 10

In previous Windows versions like Windows XP, it was possible to change the system font used in menus, Explorer, on Desktop and so on. There was an easy to use option in the GUI which allowed you to change the system font with one click. However, in Windows 10 there is no such option. The operating system lacks this ability. Here is a trick which will allow you to bypass this limitation.

By default, Windows 10 is using the font named Segoe UI everywhere in Desktop components. It is used for context menus, for Explorer icons and so on. With a simple Registry tweak, you can change it.

Open Notepad, then copy and paste the following text:

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"="DESIRED FONT"

Replace the DESIRED FONT portion with the desired font name. It can be Times New Roman, Tahoma, or Comic Sans etc - any font you have installed in Windows 10.

Right in the notepad app, you can find and copy the desired font name. Open the menu item Format - Font... and browse for the desired font as shown below:

For example, let's set the system font to the fancy Segoe Script font. The text you paste in Notepad will look as follows:

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"="Segoe Script"

Save the text you entered as a *.reg file. You can save it in any desired location with any name. Put the file name in quotes to add the *.reg extension to your file, otherwise Notepad will save it as a text file. See the following screenshot:

Now, double click the file you saved to apply the Registry tweak and change the font. Answer Yes to
all requests:

Now, sign out from your Windows account and sign in back to see the changes in action. In our case, the result will be as follows:

That's it.

To undo the tweak you applied, I prepared two ready-to-use Registry files. The first one is as described above and contains the font tweak. You can use it as a template that you can edit and substitute the desired font. The other one is "restore defaults.reg", which restores default fonts to Segoe UI. Once you merge these files, do not forget to sign out to apply the changes.
