windows 7 beta

Final Notes:
This is a limited beta opportunity to show Windows 7 to the general public in advance of its release as the successor to Windows Vista. The limitations noted in this post, primarily the lack of a clean installation option as well as the lack of a Windows XP to Windows 7 upgrade, are not representative of the final version to be sold later this year, nor are all of these limitations present in the private tester builds and MSDN/Technet releases. Rest assured, Windows 7 will be a fully functional OS and Windows XP users will not be exempted .
this was copied from c net forum also the public download will be Windows 7 ULTIMATE -- no lower editions will be released. The public BETTA expires on AUGUST 1ST 2009 at which time it CEASE to function.
