Export problem

But I can't figure out how to reply to it. I have a question:

I would like to temporarily uninstall Security Update KB3126593 run the export message function and then reinstall KB3126593 ,but it doesn't show up in my Installed Updates. I can only guess that it was superseded by a later update,but I haven't been able to identify a more recent Windows Update that supersedes it.Can someone help me to:

1. Post a reply to the existing forum article hat I posted a link to above?

If that isn't possible, I need to identify the Windows update that superseded KB3126593 so that I can temporarily uninstall it and then reinstall it after exporting my emails from Windows Live Mail? I am planning to migrate to a supported email client, but I have to be able to export all my existing emails first.
