.ANI patch can break audio applications

Reports are coming in that some users are experiencing a problem with the Windows .ani vulnerability patch I informed you about previously.

The patch is reported to break certain audio applications, specifically the Realtek HD Audio Control Panel, and CDtag, which is used for ripping music CDs.

If you are affected, you will see an “Illegal System DLL Relocation” error when you start your computer. Microsoft has issued a hotfix for the problem, which you can find here.

Microsoft regards this as an isolated incident and does not plan to issue the hotfix as part of its automatic updates.

The hotfix should be installed only if you are experiencing the problem described.
