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.
