Currently, Windows 10 20H2 (Build 19042) is the most popular version of Windows.

Last week, Microsoft announced that it had lifted the restrictions on users upgrading v2004/20H2. Today, Windows 10 v1909 (Build 18363) is officially retired and no longer accepts regular security and quality updates.

It is reported that in 20H2, Microsoft mentioned two problems left over from the v2004 era that need to be solved: one is that some Conexant audio drivers have been updated and reported errors; the other is that some Kesheng and Synaptics audio drivers have received deactivation errors and blue screens.

The affected drivers will be named Conexant HDAudio drivers in device Manager under sound, video, and game controllers, and for chdrt64.sys or chdrt32.sys, the versions are 8.65.47.53, 8.65.56.51, or 8.66.0.0 to 8.66.89.00.

The second problem is the Conexant ISST audio driver, the affected driver is called Conexant ISST Audio or Conexant HDAudio driver under the sound, video, and game controller in device Manager, and involves files uci64a96.dll, uci64a231.dll, corresponding to version 7.231.3.0 or lower.
