I attempted to install the "optional update" KB2975719 in Windows 8.1 however when the computer restarted the update failed to install and the computer would not boot correctly. After trying a number of solutions including the automatic repair and other possible solutions I had to do a restore to get the computer to reboot. However the KB2975719 remains in the update history list a pending restart. If an update is installed I can uninstall it however I can not determine a way to delete an update that is pending. I've had to do a restore twice because of what seems to be an issue with this update.
Question - how can I delete an update that is pending restart?
