Is this something Cisco has to fix or Microsoft? I cannot uninstall this patch across my environment and we are about to do a mass rollout of Jabber to replace our existing IM solution. This will cause serious problems when the complaints about performance start coming in.
Would really like to know this as well. Uninstalling the update fixed the issue for me - and in order to keep the update from installing, I have to hide it in Windows Update. Seeing that it's a cumulative security update for IE11 makes me nervous to NOT have it installed. Hopefully EMET will help mitigate not having this particular update installed.
