I've downloaded it, but I havn't installed it yet.
I want windows 7, but I don't want to have to reinstall it when Retail comes out...
When it's available you will be able to download the beta from: http://www.microsoft.com/windows/windows-7/default.aspx
Currently they have removed the download because their servers can't cope with the number of people who want it.
If you still need it, you can download an ISO of the Windows 7 Release Candidate from Microsoft's website. The download page is located here:i also need it guys
