Update: MS10-015 security update re-released with new detection logic


I am writing to let you know that we have revised the installation packages for MS10-015 with new logic that prevents the security update from being installed on systems if certain abnormal conditions exist. Such conditions could be the result of an infection with a computer virus such as the Alureon rootkit. If these conditions are detected, the update will not be installed and the result will be a standard Windows Update error. If a user receives this error, they should go to the following landing page for additional help:


At this time, we have resumed offering the update to all affected systems via Automatic Updates.

We have also released a Microsoft Fix It as a standalone scanning tool that reports on the compatibility of a system with the MS10-015 update. The scanning tool can also be deployed through enterprise deployment systems allowing administrators to detect compatibility with the update before deploying broadly. The Fix It and deployment information are available at Microsoft Knowledge Base Article 980966.

Customers who believe they have experienced a restart issue after installing MS10-015, are encouraged to visit our Customer Service and Support page at https://consumersecuritysupport.microsoft.com or call 1-866-PCSafety (1-866-727-2338). International customers can find local support contact numbers here: http://support.microsoft.com/common/international.aspx.

Update: note that the update will not be re-offered to those who have already successfully installed the update.
