Adjust “Message Text” and “Menu” to Tahoma.
Just remember to keep the “size” setting next to “Active Title Bar” to 25 to avoid the scrunch/pixelation of taskbar icons. Other good fonts are Verdana, Trebuchet MS, Lucida Sans Unicode or whatever is loaded on your system. If it’s not it will make icons in the taskbar look “scrunched” and pixelated. Then next to Active Title Bar, set to 25. Set the font to Arial and its size to 12 and bold it (the little “B” button). The Item listed will be Active Title Bar.
Where it states “Message Box”, click that. Note the “Advanced” button at the bottom right. First, go to Display Properties (“Display” icon from Control Panel), click the Appearance tab and then the Advanced button.
