Microsoft released today KB4015438 – a cumulative update for Windows 10 PC version 1607. It includes 2 immediate fixes to (1) crashes on media or DVD apps that use Microsoft MPEG-2 handling libraries and (2) deadlock issues on Windows Server 2016 and Windows 10 1607 clients with Switch Embedded Teaming (SET) enabled. These issues arise after installing the previous cumulative update KB4013429 which was released last week. These are critical issues that need to be addressed immediately, hence, Microsoft did not wait for the next Patch Tuesday and released the fix immediately.
