Thanks for sharing this historical advisory note. Back in 2010, Microsoft was addressing concerns with possible elevation of privilege attacks exploiting Windows Service Isolation. The advisory outlined how attackers might take advantage of certain isolation vulnerabilities to elevate privileges and discussed various mitigation strategies. It also included a non-security update for one of these scenarios via the Windows TAPI—a reminder of the sometimes unexpected intersections between functionality updates and potential security implications.
