Making Older Software Work in Windows 7
Applications originally written to run under earlier versions of Windows may not always per-
form well under Windows 7. One work-around is to set up Compatibility Mode for an applica-

with that application. Using the Help and Support in Windows 7, look up information about
Compatibility Mode to learn how it works and how to enable it.

, where the system requirements do not include Windows 7, and install it on your computer. As
you are locating a game to download, look at the system requirements for the game to find out the
highest Windows version it supports. Then configure Compatibility Mode to emulate that version.
Try the game to make sure it works with these settings. When you are finished, uninstall the game.
Other Software Types
There are many other software types besides the ones presented in this chapter. Using the Internet
to help provide ideas, make a list of at least seven types of software that weren't covered in this
chapter, and write a brief description of each type, including who might use it and what they
might use it for. If you can't think of seven types, look at a website that sells software, such as
Amazon.com, for ideas.

gram, and how would you make money from it? How would you provide customer support and
make sure improvements to the program were made?
