To

and change

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionID

From
Home Premium

To
Business

Insert 7 Disk and perform a normal upgrade

tested from vista home premium to windows 7 pro and vista ultimate to windows 7 pro has not been tested for home basic but in theory should work and in theory you should be able to change the word business to ultimate and go from home premium to ultimate but again I have not tried that nor have I tried to go from vista business to 7 home premium but you should be able to change those to keys and bypass the vista version issue and I believe this is a simpler solution to the Windows 7 RC upgrade but I can't try that because I already did that upgrade before I solved this issue
