When installing a third-party driver, you might receive the error, “Windows can’t verify the publisher of this driver software”. You may also see the error “No signature was present in the subject” when attempting to view the signature properties using Windows Explorer.

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.
Affected platforms:
  • Client: Windows 10, version 20H2, Windows 10, version 2004; Windows 10, version 1909; Windows 10, version 1903; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10, version 1803; Windows 10, version 1709; Windows 10 Enterprise LTSC 2016; Windows 10, version 1607; Windows 10 Enterprise 2015 LTSB; Windows 8.1
  • Server: Windows Server, version 20H2, Windows Server, version 2004; Windows Server, version 1909; Windows Server, version 1903; Windows Server, version 1809; Windows Server 2019; Windows Server, version 1803; Windows Server, version 1709 ; Windows Server 2016; Windows Server 2012 R2
Next steps: If this happens you should contact the driver vendor or device manufacturer (OEM) and ask them for an updated driver to correct the issue.

When updating to Windows 10, version 1903 or Windows 10, version 1909 from any previous version of Windows 10, you might receive a compatibility report dialog with "What needs your attention" at the top and the error, "Continuing with the installation of Windows will remove some optional features. You may need to add them back in Settings after the installation completes." You might receive this compatibility warning when LOCAL SYSTEM accounts are blocked in a firewall from accessing the internet via HTTP. This is caused by the Windows 10 Setup Dynamic Update (DU) being unable to download required packages.

Workaround: If your device has access to HTTP blocked for LOCAL SYSTEM accounts, to mitigate this issue you can enable HTTP access for the Windows 10 Setup Dynamic Update (DU) using the LOCAL SYSTEM account. After you have allowed access, you can restart installation of the update and you should not see the warning. You can also continue by clicking the OK button or use the /compat IgnoreWarning command to ignore compatibility warnings but this might also ignore other warnings that your device might be affected by.

Affected platforms:
  • Client: Windows 10, version 1909; Windows 10, version 1903
  • Server: Windows Server, version 1909; Windows Server, version 1903
Resolution: This issue was resolved in KB4579919.
