Microsoft blocks Windows 10 1809 upgrade on some PCs due to incompatible Intel drivers

Microsoft has blocked the Windows 10 October 2018 Update (version 1809) on some PCs that use certain Intel display drivers. On these machines, sound from a monitor or TV connected over HDMI, USB-C or DisplayPort may stop working after the upgrade. Microsoft added the problem to the list of known issues for version 1809 on November 21, 2018.

What is wrong with the Intel drivers

According to Microsoft, Intel accidentally released display driver versions 24.20.100.6344 and 24.20.100.6345 to PC makers (OEMs) with unsupported Windows features switched on. With those drivers installed, audio playback through a connected display may not work correctly once the PC is on version 1809.

The issue affects client and server editions alike: Windows 10 version 1809, Windows Server 2019 and Windows Server, version 1809. Microsoft says it is working with Intel on a fix. This is a separate problem from the earlier Intel Smart Sound Technology driver issue that also held back 1809.

Windows 10 1809 upgrade block: check the Intel display driver under Display adapters in Device Manager — Check your Intel graphics driver version under Display adapters in Device Manager.

How to check if your PC is affected

Press Win+R, type devmgmt.msc and press Enter to open Device Manager.
Expand Display adapters.
Right-click your Intel graphics adapter (for example Intel UHD Graphics) and choose Properties.
Open the Driver tab and look at Driver Version.

If it reads 24.20.100.6344 or 24.20.100.6345, Windows Update won’t offer you version 1809 until the block is lifted.

What to do

Wait for the fix. The block protects you from losing display audio, so let Windows Update offer 1809 when Microsoft and Intel have resolved it.
Already upgraded and lost HDMI or DisplayPort audio? Microsoft asks affected users to contact its support, which can turn off the incompatible feature for you.
Update the display driver from your PC maker or Intel once a fixed version is available; Windows Update will then offer 1809 again.

Today

Version 1809 is long gone, and Windows 10 itself reached end of support on October 14, 2025. Microsoft no longer ships security fixes for it, apart from paid or enrolled Extended Security Updates that run to October 12, 2027. If your PC meets the requirements, Windows 11 is a free upgrade through Windows Update.
