Synaptics and Microsoft have found incompatibility issues with certain versions of drivers for Conexant ISST audio driver and Windows 10, version 2004 (the Windows 10 May 2020 Update). Windows 10 devices with affected Conexant ISST audio driver might receive an error or experience issues while installing the update or after the device has updated. The affected driver will be named Conexant ISST Audio or Conexant HDAudio Driver under Sound, video and game controllers in Device Manager and have file name uci64a96.dll through uci64a231.dll and a file version of 7.231.3.0 or lower.
To safeguard your update experience, we have applied a compatibility hold on Windows 10 devices with affected Conexant or Synaptics audio drivers installed from being offered Windows 10, version 2004 or Windows Server, version 2004 until the driver has been updated. If your organization is using Update Compliance, the safeguard ID is 25178825.
Affected platforms:

Server: Windows Server, version 20H2, Windows Server, version 2004
Workaround: To mitigate the safeguard, you might need to check with your device manufacturer (OEM) to see if an updated driver is available and install it. If updated drivers are not available for your device and you are offered Windows 10, version 2004 or Windows 10, version 20H2, a small number of devices might roll back to the previous version of Windows 10 when attempting to update. If this occurs, you should attempt to update to Windows 10, version 2004 or Windows 10, version 20H2 again.
Next steps: Microsoft and Synaptics are working on a resolution and will provide an update in an upcoming release. As of January 14, 2021, we are adjusting this safeguard to allow certain devices with the affected driver to update to Windows 10, version 2004 or Windows 10, version 20H2.
