  • 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.
