Window text font size

[gazzamop]

I am trying to set the window text font size for my grandparents so that they can read text on the screen more easily. Although I can change the font size of every other system font, the window text font size is unavailable. To see this:
1. Open up Display from Control Panel
2. Click on the Appearance tab
I want to adjust the font size of the text called 'window text' under the active window. The option just isn't there in the Advanced dialog.

I've set the font size to Extra Large Fonts to no avail...

Am I being really stupid here? Or is there a special way to adjust the 'window text' font size?

Any help is appreciated!

Open your display propeties and go to settings then to advanced change the dpi setting to what you like or use the accessibility wizard in all programs menu.

Here's a couple things you can do. Go to control panel > display > settings > advanced > change dpi to 120.
If that dosnt help enough you can change the resolution to 800 by 600 in settings.
