Audio drivers deleted from certain hardware configurations

UPDATE, October 13: Bug officially acknowledged! Find all details shared by Microsoft here. Original story below.

KB4464330 is the very first cumulative update that Microsoft shipped for Windows 10 version 1809/October 2018 Update, but just like the OS version itself, it comes with several critical bugs.

In addition to creating BSODs for a number of HP systems, it looks like cumulative update KB4464330 also removes audio drivers from several computers.

I’ve seen such issues being reported on both Microsoft Community forums and reddit, but for the time being, a clear pattern hasn’t been established.

Most of the complaints point to Intel audio drivers, but there are also a bunch of users claiming other hardware is impacted too. Also, several of the reports indicate the issue takes place on HP device, but at the same time, some say that ASUS laptops experienced the same driver removal bug too.

“Last night I installed the Cumulative Update KB4464330 on to my HP laptop which is running Windows 10 Version 1809.  The install went fine and the laptop came back up.  However, when it came back up it had removed/deleted the Intel High Definition Audio device driver,” one user explains, adding that no new drivers cannot be installed after the system has been updated.

“No known issues”

Oddly enough, despite the growing number of reports pointing to problems with cumulative update KB4464330, the official KB page still claims there are no known issues at this point. Microsoft has confirmed it’s investigating the BSOD bug mentioned above.

For the time being no workaround seems to be available, so the only thing users can do to restore audio is to actually remove the cumulative update altogether.

Needless to say, this isn’t exactly the expected behavior from a new OS feature update. Microsoft is still working on finalizing the fix for the data removal bug in Windows 10 October 2018 Update, so hopefully, when it’ll be ready, the company can focus a bit more on the quality of its updates too.
