Additional Update Notes:

  • Adobe Flash Player -- For Windows Server 2012, Windows 8.1, Windows Server 2012 R2, Windows RT 8.1 and Windows 10, Adobe Flash Player is now a security bulletin rather than a security advisory and is included with the updates as identified above.
  • MSRT -- Microsoft released an updated version of the Microsoft Windows Malicious Software Removal Tool on Windows Update, Microsoft Update, Windows Server Update Services, and the Download Center.  Note:  Users who are paranoid about the remote possibility of a FP can opt to run this tool from a Command Prompt, appending a   /N   parameter [for "detect only" mode].
  • Servicing Stack Updates -- A list of the latest servicing stack updates for each operating system can be found in ADV990001. This list will be updated whenever a new servicing stack update is released. It is important to install the latest servicing stack update. 
  • Windows 10 updates are cumulative. The monthly security release includes all security fixes for vulnerabilities that affect Windows 10, in addition to non-security updates. The updates are available via the Microsoft Update Catalog.
  • Updates for Windows RT 8.1 and Microsoft Office RT software are only available via Windows Update.
