Microsoft released the September Cumulative Update (KB3081455) yesterday. If you haven’t been prompted to install it yet, assuming you haven’t deferred updates, you will be soon.
This cumulative update addresses issues from multiple security bulletins and includes security fixes for Internet Explorer, Edge, and fixes for vulnerabilities that could allow an attacker to remotely run code on your system.
Unlike some past cumulative updates, no new features were added by this update. It’s just security fixes.
Keep in mind that in order to install this particular cumulative update on a Windows 10 system, you will be required to already have KB3081448 installed. If you don’t, you’ll have to allow it to install first.
