Font usage in under OEM Windows License

If I make and sell a hardware product that has PC in it, and I pay for a Windows OEM license for each unit, does the OEM license for that Windows install include the usage of the fonts that ship with Windows? The product has an app on it that I make to run the hardware , and the app runs on the Windows OS install that I paid for. The app calls to the Windows OS to display fonts that were included in the Windows OS. The hardware device is standalone and only displays the fonts on the one unit that has the Windows install. Does that require a separate font license?

    Hi Bill Benoit,

    You are correct about the licensing model. When you purchase and apply a valid Windows OEM license to your hardware unit, the fonts located in the C:\Windows\Fonts directory are fully licensed for use on that specific local device. Because your application simply makes standard calls to the native Windows rendering engine to display text on the unit's standalone screen, you are utilizing system-resident assets exactly as intended by the operating system. This standard rendering function does not constitute font redistribution and requires no additional licensing.

    A separate font license is only legally required if you copy, extract, or bundle those actual font files directly into your application's installation package, or if you attempt to deploy them to an unlicensed operating system. As long as your configuration relies exclusively on the locally licensed Windows environment to render those fonts, your existing OEM license provides complete legal coverage.

    Windows fonts that are supplied as system-wide resources can be used by applications running on that licensed Windows installation to render text to the device’s screen or to output devices such as printers. This is explicitly allowed as part of normal use of Windows fonts.

    The guidance for Windows-supplied fonts states that:

    • Any application installed on a Windows computer can use these fonts to render, edit, and output content.
    • There are no additional restrictions on what is done with printed or bitmap-rendered output (for example, UI text, logos, captions in videos), as long as the font files themselves are not redistributed or embedded in non-document scenarios.
    • Redistribution of the font files themselves, conversion to other formats, or embedding fonts into apps, games, or devices (beyond document embedding rights) is not allowed without obtaining extended rights from the font owner.

    In the described scenario:

    • The app runs on a properly licensed Windows OEM installation on each device.
    • The fonts are only used to render UI and text on that same device.
    • The font files are not being copied off the Windows installation, redistributed, or embedded into the app or device firmware as standalone assets.

    Under these conditions, no separate font license is required beyond the valid Windows OEM license for that device. A separate font license would be required only if the fonts were to be redistributed (for example, shipped with the app or device outside of the Windows installation) or converted/embedded in ways that go beyond normal on-device rendering.
