This month there are seven bulletins, with related patches affecting Internet Explorer, Windows and Office. A total of sixty-six security vulnerabilities are fixed with these updates.
Note that Microsoft is recommending upgrading to the latest version of Internet Explorer. IE 11 contains security features not found in previous versions and is therefore somewhat more secure than those older versions. Anyone still using Internet Explorer would do well to follow this advice.
Note also that this is the last set of updates that will be available for Windows 8.1 installations without Update 1. In other words, if you’ve held off on installing Update 1, you won’t get any updates next month or after that.
