Enterprise rollouts of Windows 8.1 updates through the Windows Server Update Service is hitting a bit of a roadbump. Apparently servers running SSL but without Travel Layer Security 1.2 enabled won’t be able to push out the update, and Microsoft is pausing the distribution of the update until this is fixed. This doesn’t stop you from updating if you haven’t already, since you can pick it up from the Windows Update Catalog, but Microsoft still suggests you wait until a fix is in place.

From a recently-published knowledge base article:

”Microsoft plans to issue an update as soon as possible that will correct the issue and restore the proper behavior for Windows 8.1 Update KB 2919355 scanning against all supported WSUS configurations. Until that time, we are temporarily suspending the distribution of the Windows 8.1 Update KB 2919355 to WSUS servers.”

Enterprise administrators controlling their own update servers simply need to enable TLS 1.2 to get rolling again. Has anyone hit this issue in their workplace?
