Did you hear the one about eMudhra and the power of 4? Time to get connected to certificate trust list updates

Microsoft has released another out-of-band update for Windows, but this one isn't an emergency fix for the latest breakages. This time, it's all about certificates.

The non-security out-of-band release applies to supported OSes ranging from Windows 11 and Windows Server 2025, to Windows 10. It's all about updating the current certificate trust list (CTL) of devices that cannot access Microsoft's certificate-update service, or where automatic CTL updates are disabled.

It also contains everything in the October 13 update, including the ongoing VPN issues and the change that could break on-premises Exchange Servers .

There might also be oddities with Smart App Control, audio, and Remote Desktop connections for non-admin users, all of which are known issues in the October 13 update.

These problems are not resolved in this patch, so be aware of this when installing it.
