No, and Microsoft made it pretty clear early on that there was NO upgrade path for those pre-release versions of Windows. You will have to do a fresh/clean install.
Some time ago, I upgraded my computer with WinXP Home to the 7000 build of the Win7 Beta. I just purchased an upgrade copy of Win7 Home, but apparently I can't upgrade because the upgrade thinks I have a full version of Win7 Ultimate. Is there anyway to get around this? The computer came with WinXP, so I don't have the authentication codes or the discs. How can I get around this?
Thanks.
