Microsoft May 2017 Security Bulletin

The May security release consists of security updates for the following software: Internet Explorer, Microsoft Edge, Microsoft Windows, Microsoft Office and Microsoft Office Services and Web Apps, NET Framework and Adobe Flash Player.

This is the first batch of updates that are no longer available for Windows Vista, as support for this OS has ended as of April 11, 2017, some 10 years after it was first released. It is also the last patch day for Windows 10 RTM (version 1507), with updates continuing for the Anniversary Update (version 1607) or the Creators Update (version 1703).

More details about the updates can be found on the Microsoft Security Portal
