We had users complaining about needing to upgrade to IE11, they were running IE8,9, and 10. I tracked down the KB that was installed on patch tuesday to: KB3124275. We have users who have to use Internet Explorer 10 for specific applications, so we cannot ugprade. I removed it from SUS and users PC’s, hopefully this’ll save someone some time.
You can see the MS KB here: https://support.microsoft.com/en-us/kb/3124275
And note part of the way down it says the GR KB is here:
KB3123303 The new “End of Life” upgrade notification for Internet Explorer
