Additional Update Notes:

- 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. 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.
