Various Issues After Installing Microsoft Security Bulletin MS05-051 on Systems That Have Non-default File Permissions

Published: October 14, 2005

Microsoft is aware of reports of isolated issues after deployment with Microsoft Security Bulletin MS05-051. We are working with a limited number of affected customers to help resolve these issues.

Systems that do not have the default Access Control List (ACL) settings in the %Windir%\Registration folder may experience various problems after installing MS05-051. The update helps protect against attacks seeking to exploit MS05-051, however this isolated set of issues might impact systems after installation of the update.

Based on feedback from those customers, Microsoft has published Microsoft Knowledge Base Article 909444, which addresses the issue.

We continue to urge customers to deploy MS05-051 and all recent security updates. For additional information about security updates, please visit the following Web site.

Product Support Services in North America can be contacted for help with security update issues or viruses at no charge by using the PC Safety line (1-866-PCSAFETY).
