Microsoft Halts Windows 10 October Update Rollout Yet Again, Affects Only Some Intel Users
Microsoft has blocked rollout of the Windows 10 October 2018 Update on systems using Intel Integrated Graphics with specific driver versions. Apparently audio playback, when using a monitor connected to the IGP, will no longer work after the upgrade to October Update.
According to Microsoft, the underlying reason for the issue is that "Intel inadvertently released versions of its display driver [...] to OEMs that accidentally turned on unsupported features in Windows."
If you want to work around this, then check your Intel driver version using GPU-Z. If you see "24.20.100.6344" or "24.20.100.6345", just upgrade your graphics drivers and you should be good to go.
