How to restore the original system font in Windows

If so, reset the "Restore Default" option of the tool; if no tool is available, you can manually locate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Fonts through the registry editor to ensure that the font value of SegoeUI is correctly pointed to segoeui.ttf and other files, and back up the registry if necessary; then run the command prompt as an administrator and execute the sfc/scannow command to repair the system files; finally go to Settings → Personalization → Theme, and select Windows to light it by default.
