heilo, on 1/13/16 my windows 7 laptop tried to install 11 updates. the next time I booted up I got message "Failure configuring Windows updates. Reverting changes. Do not turn off your computer". this happened 2 more times over the next day, and then the message stopped. looking in the update history it showed that 10 of the updates were a success, but 1 failed - security update for windows 7 for x64-based systems (kb3108664). the failed update logged error code 80071a2d. do I need to be concerned about this? any help would be greatly appreciated! thanks!
