Microsoft earlier this week released Windows 10 October 2018 (version 1809) update. You can either get it through Windows Update, and install it leaving your personal files and settings largely unchanged, or perform a clean install by making yourself an install media using Microsoft's Media Creation Tool. PC Watch noticed something curious about getting the new Windows version through Windows Update on their notebook. The process was sapping too much power from the battery, and the update process is interrupted by an incompatible driver dialog (screenshot below).

Intel processors running with Gen 9.5 iGPUs enabled (that's 6th generation "Skylake" or later), expose an integrated audio controller to the operating system. This controller is responsible for digital audio output through the iGPU's HDMI and DisplayPort connectors, and is similar to the one NVIDIA and AMD integrate with their discrete GPUs. Users with driver version 10.25.0.3 or older for this controller, could run into problems when Windows Update is re-loading the drivers as part of the upgrade process. Intel has since released driver version 10.25.0.10 part of the latest Graphics Drivers 25.20.100.6323. If you're still on Windows 10 version 1803 and use your iGPU, it's recommended that you update your Intel graphics drivers before initiating Windows Update to version 1809.
