The download link for Windows 7 RC (Release Candidate) would be unavailable post August 20, 2009. If one has a physical media (DVD, downloaded bits), they can still install post this date but the download option would not be available.
Windows 7 RTM would be available before end of this year and it should also be available in stores etc., by then. This post is just to create awareness that if you would like to install and play with Windows 7 RC, do it right away before the download becomes unavailable.
The Windows 7 Download page and product key page is http://www.microsoft.com/windows/windows-7/download.aspx
The Windows 7 Forum is http://social.technet.microsoft.com/Forums/en/category/w7itpro/
Let me now share my experience with Windows 7. It is purely unbiased and is a what is what, I have experienced with Windows 7 RC over the past few months.
I have been running my production machine on Windows 7 RC and haven't had a single crash, failure so far. I leave the machine on over night, for long hours and its battery consumption is optimal. Compatibility with applications and drivers has never been an issue. Whatever works on Vista, works here.
The Start-up and Shut Down duration has significantly improved compared to Windows Vista (Ask me why and I will explain). Visual Studio 2008, 2010, all the various CTPs I play with have all worked without having to install a separate version tailored to Windows 7.
Over the last 10 years, this has been the most stable operating system I have used (believe me, I have used various OSes including non Microsoft ones') at the RC level.
So, if you are still unable to believe, try it for yourself and you will see the difference.
Cheers !!!
