No it has not been fixed as my computer exploded only but yesterday with that same critical error as mentioned. This was the first time it did so however I have only recently upgraded to WIN 10. After a long while of combing web on tablet I found and obscure entry regarding getting rid of avast to fix problem, therefore I had to uninstall it after many years of use. Win 10 immediately works again following Avasts removal. What happens now as to all my subscriptions :-\
