Check out this blog entry talking about the default font in Forms which leads to the problem you are experiencing and this Connect Bug with Microsoft's response. In short it just seems that Forms does not get the (correct) default windows font (which you have changed).

The controls inside the group box are indeed not affected by the form's Font property. The reason is that controls in container controls are treated as children of the container controls like groupbox, but not children of the main form. In order for all controls including those in groupboxes to scale properly, you can use code similar to below:

        foreach (Control ctr in this.Controls)
        {
            ctr.Font = SystemFonts.IconTitleFont;

            // controls in groupboxes are not child of main form
            if (ctr.HasChildren)
            {
                foreach (Control childControl in ctr.Controls)
                {
                    childControl.Font = SystemFonts.IconTitleFont;
                }
            }        
        }
