First, let me say I searched this forum for 'KB2267602' and did not see any results.
Issue: Windows Update KB2267602 fails to install and Windows Defender cannot run.
It appears as though Covecube is aware of this issue based on the following comment in this code change:
Is there an update to when this issue will be addressed? I don't like having Windows Defender unable to run on my PC, and it seems like Windows Update has stopped searching for new updates as well. Thanks.
