Microsoft Corp. on Wednesday said that customers have convinced it to flesh out the monthly advance notice of impending security updates with more information. Beginning in June, the advanced notice will offer more detail than before, Mark Miller, director of the Microsoft Security Response Center (MSRC), said on the group’s blog. Rather than earlier bare-bones guidance, which was limited to the software affected — Windows or Office, for instance — and the maximum severity rating of all the updates, the MSRC will now summarize each bulletin separately the Thursday before patches are issued.
