According to Microsoft’s Security Update Guide, March’s updates, twenty-eight in all, include fixes for at least sixty-five security vulnerabilities in .NET, Flash Player (in IE and Edge), Internet Explorer, Edge, Office, Visual Studio, and Windows.

Even if you have automatic updates enabled on Windows 7 and 8 computers, it’s a good idea to check for and install the new updates. If you’re running Windows 10, auto-updates can’t be disabled, but you can still check for updates, and get them sooner that way.

There are no updates for Flash or Reader from Adobe so far in March.
