The monthly patch update contains patches for Windows Me/98, Windows Server 2003 and XP SP1 and SP2.
One critical patch, Security Bulletin MS05-010, concerning a flaw in Microsoft's License Logging Service, was issued for the now unsupported Windows NT 4.0 server platform.
This latest update comes a month after Microsoft issued another patch for NT4. At the time the company said, "On this rare occasion, we believe that this vulnerability presents a serious risk to a broad number of customers. We determined that the best course of action to help protect customers was to release this security update."
