Microsoft quickly encouraged users to remove the stricken update and worked on a fix instead. In actual fact, the fix just removes the previous update.
The new update - KB3024777 - will remove the previous update from your installation and should fix any problems you have after a reboot or two. Depending on your Windows Updates settings you might already have gotten the update (and will have been prompted to reboot), or you may have been alerted to its availability instead.
You can manually download the update for your Windows operating system from support.microsoft.com too.
