The link you referred only states:
This behavior occurs because Windows automatically closes any registry handle to a user profile that is left open by an application. Windows Vista does this when Windows Vista tries to close a user profile.

In versions of the Windows operating system that are earlier than Windows Vista or Windows 7, you must install the User Profile Hive Cleanup Service (UPHClean) utility to have the same functionality. However, the UPHClean utility is incompatible with Windows Vista and Windows 7. Additionally, the UPHClean utility is not needed because this functionality is built into Windows Vista.

Note Event ID 1530 is logged as a Warning event. The application that is listed in the event detail is leaving the registry handle open and should be investigated.

There is no solution.

You have it backwards. The link you referenced is the where this problem was first mentioned. This link was the continuation of that link where I separated event ID 1530  from the other event IDs listed.
