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].

Windows 10 -- A summary of important product developments included in each update, with links to more details is available at Windows 10 Update History. The page will be regularly refreshed, as new updates are released.
