Microsoft Update Creates Error

Last week I loaded the April 3 Security Update from Microsoft onto my work computer.
http://www.microsoft.com/athome/security/update/bulletins/200704OOB.mspx

This update was marked as Critical and was released early just to get it in circulation. Unfortunately it created a .dll conflict error.

RTHDCPL.EXE – Illegal System DLL Relocation
The system DLL user32.dll was relocated in memory. The application will not run properly. The relocation occurred because the DLL C:\system32\HHCTRL.OXC occupied an address range reserved for Windows system DLLs. The vendor supplying the DLL should be contacted for a new DLL.

In all my years of computing I have never before seen that error. I restored my system to an earlier date and again loaded the update with the same results. I searched in vain on the Microsoft website to find an explanation for this error. While the computer seemed to perform correctly, I wanted to be sure my system was ok.

I looked up all the .dll files mentioned in the error message and found that the one triggering the error was a RealTek audio driver. I went to the RealTek site and downloaded their HD audio update and I no longer get the error message.

Why there was conflict between Microsoft and RealTek I don’t know but I hope the security update was really that important.

UPDATE
