Hi I need to enable/disable Cleartype (or \"Adjust the appearance and performance of Windows > Smooth edges of screen fonts\") via cmd (or any script like VBS/JS) or from re

Answer 1

Just to add more options, I have the C# version, adding GetFontSmoothing to it.

    [DllImport("user32.dll", SetLastError = true)]
    static extern bool SystemParametersInfo(uint uiAction, uint uiParam, ref int pvParam, uint fWinIni);

    const uint SPI_GETFONTSMOOTHING = 74;
    const uint SPI_SETFONTSMOOTHING = 75;
    const uint SPI_UPDATEINI = 0x1;
    const UInt32 SPIF_UPDATEINIFILE = 0x1;

    private Boolean GetFontSmoothing()
    {
        bool iResult;
        int pv = 0;
        /* Call to systemparametersinfo to get the font smoothing value. */
        iResult = SystemParametersInfo(SPI_GETFONTSMOOTHING, 0, ref pv, 0);
        if (pv > 0)
        {
            //pv > 0 means font smoothing is on.
            return true;
        }
        else
        {
            //pv == 0 means font smoothing is off.
            return false;
        }
    }

    private void DisableFontSmoothing()
    {
        bool iResult;
        int pv = 0;
        /* Call to systemparametersinfo to set the font smoothing value. */
        iResult = SystemParametersInfo(SPI_SETFONTSMOOTHING, 0, ref pv, SPIF_UPDATEINIFILE);
        Console.WriteLine("Disabled: {0}", iResult);
    }

    private void EnableFontSmoothing()
    {
        bool iResult;
        int pv = 0;
        /* Call to systemparametersinfo to set the font smoothing value. */
        iResult = SystemParametersInfo(SPI_SETFONTSMOOTHING, 1, ref pv, SPIF_UPDATEINIFILE);
        Console.WriteLine("Enabled: {0}", iResult);
    }
