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. Note, however, that there are no Adobe Flash Player security updates for Active X.
  • MSRT -- The Malicious Software Removal Tool is now run on a quarterly basis rather than monthly.  See Remove specific prevalent malware with Windows Malicious Software Removal Tool.
  • 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. Learn more about SSU's in Servicing Stack Updates (SSU)
  • 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 also available via the Microsoft Update Catalog.
