Problems with Realtek HD Audio Control Panel

I recently wrote about a vulnerability in the way that Windows handles animated cursors, and that Microsoft were releasing a patch for the problem. I downloaded and installed the patch yesterday, and discovered that it didn’t like my sound card all that much.

My HP desktop has a Realtek sound card, and the patch that MS released prevents the control panel for the sound card from loading, with the following error message:

The system DLL user32.dll was relocated in memory. The application will not run properly. The relocation occurred because the DLL C:\Windows\System32\Hhctrl.ocx occupied an address range reserved for Windows system DLLs. The vendor supplying the DLL should be contacted for a new DLL.

Fortunately, there is a fix available form Microsoft, available under KB 935448
