After the release of every major Windows 10 version, we see lists of user-reported bugs going up. With the last two versions, Microsoft has itself been proactive, publishing lists of known issues as soon as a new version goes live. With the latest Windows 10 October 2020 Update, version 20H2, this list brought forward bugs initially discovered in version 2004.

Windows 10 v2004 is the last major version of the operating system, which has been followed by v20H2 and the upcoming v21H1. Initially added to the list of known issues back in May 2020, Microsoft had reported a problem with select Conexant and Synaptics audio drivers, putting safeguard holds on impacted devices.
