Known issues with this security update

This security update opts Microsoft Word, Excel, or PowerPoint into local computer lockdown, a feature control for Internet Explorer, to prevent scripts in Office documents from running with elevated user rights.

Specifically, in a side-by-side scenario of Office 2003 and either the 2007 Microsoft Office suite or Office 2010, the changed registry keys in this security update may also affect Office 2003. This may cause some unexpected behavior in Office 2003.

Workaround

ActiveX kill bits may be used to completely block ActiveX controls that could lead to HTML script execution.
