Lync 2013 / SfB 2015 Client Update – February 2019

We have a February update! It’s been just over a month since our last update to the client, and as with January’s, this update also only brings one fix. Kb 4462135 takes the Office 2013-based client from 15.0.5101.1000 to 15.0.5111.1000.

What’s Fixed

This update fixes the following issue:

  • 4488496 Call or conference window becomes transparent in Skype for Business.

What’s New / Changed

Nothing documented.

Known Issues

Nothing documented.


It’s all good if you’ve been diligent in your patching.

If however your patching isn’t to current you’ll need to check you have *all* of these pre-req’s. The Office 2013 SP1 requirement still applies if you’re using Outlook 2010. (Lync 2013 in all of its flavours – e.g. Lync Basic – is still a component of Office 2013).

This is the client fix itself:

  • x86 (lync2013-kb4462135-fullfile-x86-glb.exe)
  • x64 (lync2013-kb4462135-fullfile-x64-glb.exe)


I have all the pre-req’s already installed, had exited the client before we started & was not prompted for a reboot.
