Microsoft has issued an out-of-band non-security update to address an issue triggering SSL/TLS handshake failures on client and server platforms.

"We address an issue that might affect some types of Secure Sockets Layer and Transport Layer Security connections. These connections might have handshake failures," Microsoft explains.

You can install them by downloading from the Microsoft Update Catalog and manually importing them into WSUS and Microsoft Endpoint Configuration Manager.

The company is still working on a fix for Windows 10 2016 LTSB, Windows Server 2016, and Windows 10 2015 LTSB. After deploying the update, the Cluster Service might fail to start because a Cluster Network Driver is not found due to an update to the PnP class drivers used by the service.

Last month, Microsoft said that it accidentally listed the September Windows preview update in Windows Server Update Services.

Redmond added that until the update was removed from WSUS, it could still lead to security update install problems in some managed environments.
