When I want back and checked for Windows updates, KB4074588 started to download again and reported “Awaiting restart”. The problem started when Windows Update reported that KB4074588 was available with the “ Awaiting restart” status.Īfter restarting, I got the “ We couldn’t finish installing updates” notification message. The error code for the failed installation was 0x80070bc2. I just ran into a problem installing the KB4074588 update on Windows 10 and would like to share how I solved the problem.
