Event ID 1530 :: User Profile Service

My Experience:
This warning appeared multiple times in my event log:

Windows detected your registry file is still in use by other applications or services. The file will be unloaded now. The applications or services that hold your registry file may not function properly afterward.

DETAIL -
1 user registry handles leaked from \Registry\User\S-1-5-21-793170598-2248495922-3383009104-1011_Classes:
Process 972 (\Device\HarddiskVolume2\Windows\System32\svchost.exe) has opened key \REGISTRY\USER\S-1-5-21-793170598-2248495922-3383009104-1011_CLASSES


The Cause:
It is a side effect of upgrading directly from XP to Vista. There is an old utility UPHClean which is trying to do the same thing that was built into Vista. More information here.

The Fix:
Sadly, there is no fix, but it's simply how the operating system works. Do note that not all 1530 events are the same. The ones from winlogon.exe and svchost.exe can be safely ignored because this is normal behavior.

My Results:
Though it is adding to the numbers of events I have in my loge, I'm having no issues.
