Hi
If you are using Internet Explorer, press the Alt key to show the Menu Bar and select View/Text Size. Select a size that that is comfortable for you.
For the Desktop, you will need to change the DPI settings.
Right click the Desktop and select Screen Resolution.
In the next window, select Make text and other items larger or smaller.
In the next window, select one of the optional sizes or set a Custom size to suit your needs.
Hope this helps.
Thank You for using Windows 7
