    Windows 11 does not provide a supported way to change the system font to an arbitrary font through Windows settings. In modern Windows, registry-based system font customization is deprecated and the system no longer reliably applies those changes.

    What is supported in Windows 11:

    1. The default system font is Segoe UI Variable.
    2. If text appears wrong or unreadable because of a prior font modification, reset the font settings back to default rather than trying to substitute another system font.
    3. If the issue is that certain characters or languages are missing, add the needed language-associated fonts or supplemental fonts instead of changing the system font.

    To add missing language fonts in Windows 11:

    1. Open Settings.
    2. Go to Time & language > Language & region.
    3. Under Preferred languages, select Add a language if the needed language is not installed.
    4. Install the language features.
    5. If needed across the system, select it under Windows display language and sign out to apply it.

    To add supplemental fonts without changing the display language:

    1. Open Settings.
    2. Go to System > Optional features.
    3. Select View features next to Add an optional feature.
    4. Select the supplemental font package needed.
    5. Select Next, then Add.

    Important: adding languages or optional font features uses Windows Update, so the device must be online.

    Though you can change system font using registry, the older method, but it's no longer working efficiently. You may result in many portion of the OS font remain unchanged even after altering system font using registry.

    Hence, there is no effective method available to completely change system font in Windows 11.

    Thanks for your understanding!
