I am unable to update to Vista SP2, but don't care unless it prevents me from upgrading to Windows 7.  I know I can do a clean install, but would like to preserve my settings and as much of what I currently have on my Vista machine.  My current computer is homebuilt and the full Vista Premium was installed................I have the disc, it is not a preinstalled O/S from dell or HP.  I have searched for cures to the Vista SP2 upgrade problem but nothing works.  So the question is can I upgrade to Windows 7 over Vista with SP1?
