If you have Windows Vista:

-Right click your desktop back ground and select "Personalize"

-In the left hand menu of the window that opens up, select "Adjust font size (DPI)"

-There you will see the option for larger font for reading (120 vs. the default 96DPI).  You will need to click apply and save to put the setting in place.

Now, if you want to make it larger in your IE browser, open up Internet Explorer and push your "ALT" key on the keyboard.  There should be a menu at the top, select "View" and then "Text Size" where you will see the options there to make them larger.

If you want to make object and everything larger you can change your computer's resolution (but it may cause the images to be less sharp), to do this with Vista:

-Right click your desktop back ground and select "Personalize"

-Click the option at the bottom for "Display Settings"

-In the new window that pops up you will see a slider bar which you can slide to the left for a lower resolution which if you don't like you can change back.  You will have to apply and save the settings.  You will want to keep the same ratio or it might stretch the images or leave black lines on the side or top and bottom.
