If you want to increase the size of your font in Vista or Windows 7, it's just a couple clicks away. To do so in Vista, right click your desktop and choose Personalize. Then in the left pane, click on the Adjust font size (DPI) link.
After you do that, a User Account Control warning might pop up asking for your permission to continue. Just hit the Continue button and move on. (That is only there because you're changing something on your computer and they want to make sure it really is okay with you). Next, click the option that says "Larger scale (120 DPI) - make text more readable." When you're all finished, click OK.
The quickest way to access this in Windows 7, is to type display into the Start search box. Click on Display.
You can then select from 3 sizes. This will increase the size of everything on the screen. Check the one you want and click Apply.
If you just want to increase the font size, click the Set custom text size link at the left. Here, you can either slide the rule, or type in a percentage increase.
You should see an instant change, but you can check it out even further by opening up your Web browser and going to your favorite Web site. Or maybe open up a document you've been working on. Either way, the font size will be much larger and you will no longer have to strain your eyes to see what's written. Increasing the font size will reduce the number of headaches you get while working on your computer and you'll just be happier all the way around. It doesn't get any better than that!
