If you want things bigger permanently, you need to go to the Appearence applet of the Control Panel. As you seem to be aware, there're other ways to make things larger like CTRL+ in browsers, but for permanent changes, you need to use the Control Panel.
This morning I turned on my computer and all objects and text were so tiny I can hardly read anything. I use Windows XP. I've seen the temporary solutions for increasing size, such as using the mouse wheel, but I'd to restore the computer to normal size everywhere rather than tinkering with each web page as I go along. I tried to increase the screen resolution in the control panel but it's already set to max size: 1920 by 1080 pixels.
