It seems after a lot of testing this is a Windows 7 Enterprise only issue. Possibly because of Domain logon where users are limited in the way they can log in and use the workstation (although I am not able find any Microsoft documentation to verify that). Maybe Microsoft provides the HKCU key for domains where the user may not or the computer may not have the rights to run HKLM. As far as I can tell the HKCU key does not exist in any other version of Windows 7, plus it is only there when the Windows 7 Enterprise machine is added to a domain.
Maybe CCleaner can scan the key, if it does not exist ignore, it if it does then show whatever is in the key in the STARUP??
I thank you for all your help.
