Microsoft has partially addressed known issues impacting Windows 10 devices with certain Conexant or Synaptics audio devices after investigating ongoing errors since May 2020. Microsoft has also removed some of the safeguard holds blocking the affected systems from upgrading to the latest Windows 10 version.

Users are advised to use this update problem troubleshooter or this guided walk-through.
