Earlier today, PCs in the Production Ring started updating automatically with the latest cumulative update for Windows 10, build 14393.969, otherwise known as KB4015438. Compared to the changelogs from last week, this latest PC Production Ring build only has a couple of bug fixes, mainly regarding the update we saw last week.
- Addressed a known issue with KB4013429 that caused Windows DVD Player (and 3rd party apps that use Microsoft MPEG-2 handling libraries) to crash.
- Addressed a known issue with KB4013429, that some customers using Windows Server 2016 and Windows 10 1607 Client with Switch Embedded Teaming (SET) enabled might experience a deadlock or when changing the physical adapter’s link speed property. This issue is most commonly seen as a DPC_WATCHDOG_VIOLATION or when verifier is enabled a VRF_STACKPTR_ERROR is seen in the Memory dump.
