Since the release of Windows 10 May 2020 Update, version 2004 earlier this year, Microsoft has chosen to be more upfront about what issues to expect from a new feature update. While this helps in reducing dread over the new update, it also makes users question why would the company not remove these issues before the public release.

In the case of Windows 10 October 2020 Update, it seems like version 20H2 is inheriting the issues of version 2004 that are yet to be resolved.

Here is the current list of Windows 10 October 2020 Update known issues

1- When installing incorrectly formatted third-party drivers, you might receive an error (Tagged as Resolved)

Microsoft has recommended users to contact the driver vendor or device manufacturer (OEM) and ask them for an updated driver to correct the issue.

This issue occurs when one or more of the following is present in a driver package:

  • an improperly formatted catalog file is identified during validation by Windows. Starting with this release, Windows will require the validity of DER encoded PKCS#7 content in catalog files. Catalogs files must be signed per section 11.6 of describing DER-encoding for SET OF members in X.690.
  • a driver catalog file extension is not one of the supported extensions.

2- Errors or issues during or after updating devices with certain Conexant audio drivers (Tagged as Investigating)

This issue is coming from version 2004. The Windows maker said that it has applied a compatibility hold on Windows 10 devices with affected Conexant or Synaptics audio drivers. Microsoft added that it’s working with Synaptics “on a resolution and will provide an update in an upcoming release.”

3- Errors or issues during or after updating devices with Conexant ISST audio drivers (Tagged as Investigating)

Similar to above issue, currently causing a safeguard hold for affected devices.

4- Issues when using Microsoft IME for Japanese or Chinese languages (Tagged as Mitigated)

Workaround steps are shared in this support document.
