I was just wondering whether it has been confirmed or not from Microsoft that those who are running the RC of Windows 7 can just upgrade to the proper release instead of performing a clean installation?
If you can upgrade from the beta to the RC (insert the disc, open the installer from the disc in Windows 7 and select upgrade) then I don't understand why you wouldn't be able to in the actual release.
well,a its generally impossible to upgrade from windows 7 rc to its official release,because by that way,microsoft will suffer huge moneyloss and many people will get to know that there is not much difference in beta and official release,so i would say get a proper release on october 22 and make a clean install of it
