Windows 11 is a good-looking operating system but people love to make things personal and to their liking so we decided to help you in this mission with small customization of changing default system fonts inside Windows 11.
Since there is no really easy way to just switch the font windows is using for itself we will have to tweak a registry a little so before we start please do make a backup of the registry file and follow the steps as they are presented in order to avoid any errors and break the system.

So, if all precautions are made and you are ready to change your Windows appearance let's dive right into it:
There are vast free font sites on the internet where you can find fonts that you like and wish to use but be very careful with your desired font selection. The font that you choose needs to be a complete typeface, meaning that it has to contain all glyphs, large and small font sizes, all special characters, etc or you will experience that in certain areas nothing will be displayed.
Once you have found the font that you like and made sure it is a complete font, install it on your system (you can skip this step if you just want to change the system font with one already installed on your system)
Open notepad or a similar plain text editor in order to create a file that will apply changes directly into the registry and create a new file. Inside the file paste this 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"="NEW-FONT"
All the way to the bottom where it says: "Segoe UI"="NEW-FONT", change NEW-FONT with the font name that you have chosen or installed in the previous step. For example: "Segoe UI"="Ubuntu".
Now go to File > Save As and name your file however you want but give it REG extension so it looks like: my_new_windows_font.REG
Now that you have your registry entry saved, locate it and double-click on it, at this stage Windows warning will probably pop up, you can just ignore it and click on YES since you wrote the file and know what it is. After registry entry is applied reboot your PC in order for changes to take effect.
If you want to change the font to another one, just repeat this procedure again. If you want to roll back to using the default Windows font, repeat the process but with this code instead of the one provided in the REG file:
