There's a lot of information available on the Internet, as you already know. What you don't appear to know is that it's easy to find. There are a lot of Internet search engines available, of which the most well-known is Google (just put in www.google.com and it will redirect to your local Google). Give it a try.
ok you want to install websphere 6 on windows. So next would be which windows: xp or vista or 7. XP with SP2 is fine. vista and 7 face installation problems. Next step is to search for a folder called WAS in the Websphere 6 folder. In the WAS folder find the install icon. Double click on it and follow the GUI wizard instructions for the installation. Mostly it is next... next but slightly tricky. I think this would help you for now.
