Apparently, last week’s security updates caused a couple of new problems which have now (hopefull,) been fixed.
The new cumulative update for Windows 10 version 1607 (Anniversary Update) KB4015438 patches two issues introduced by last week’s Patch Day. This raises the version of the Anniversary Update version of Windows 10 to 14393.969. The KB4015438 update seems to fix two issues introduced last week that affected some users of the operating system after devices were updated with last week’s security updates.
The first issue caused programs that use Microsoft MPEG-2 handling libraries to crash (e.g. Windows DVD Player). The second issue listed by Microsoft affected customers with Switch Embedded Teaming (SET) enabled who “might experience a deadlock” according to Microsoft.
