Find out which operating system and which browser version you are using
Windows:
Right-click on the My Computer Icon (it may be on your desktop or it may be inside the Start Menu) and choose “Properties”. The box that opens up will tell you what operating system and what version you are using.
If you use Internet Explorer on a PC, choose Help > About Internet Explorer from your browser's top menu. If you use Netscape Navigator, choose Help > About Navigator. In either case, the window that pops up will tell you which version of the browser you have.
Macintosh:
On a Mac, here's how to find out which version of Mac OS you're running. Click on the Apple icon in the upper left corner of your screen. Then select "About this computer." In the pop-up screen, you should see something like "OS 9.1" (for Operating System version 9.1).
Apple recommends using Safari as your web browser if you have OS X. If you have Netscape on your Mac, open the program and click the Apple icon in the upper left corner of your screen. Then select "About Communicator" to find out which version you're running.
