Summary
Microsoft and Intel have identified a compatibility issue with a range of Intel Display Audio device drivers that may result in excessive processor demand and reduced battery life. As a result, the update process to Windows 10 October 2018 Update (version 1809) will fail. If you see a “What needs your attention” notification when you run the October Update, you have an Intel Display Audio device driver (intcdaud.sys, versions 10.25.0.3 – 10.25.0.8) installed in your system.
Important: On the notification, click Back to remain on your current version of Windows 10. (Do not click "Confirm", as this will proceed with the update and you may experience compatibility issues.)
To ensure a seamless experience, we are blocking devices from being offered Windows 10 version 1809, until updated Intel device drivers are installed on your current operating system. We recommend that you do not attempt to manually update to Windows 10, version 1809, using the Update Now button or the Media Creation Tool from the Microsoft Software Download Center until newer Intel device drivers are available with the update. You can either wait for newer drivers to be installed automatically through Windows Update or check with your computer manufacturer for the latest device driver software availability and installation procedures. For more information about this issue, see Intel's customer support guidance.
This page will be updated when the block has been removed.
