What version of Windows 10? I would advise you copy it from existing functional Windows 10 System32 folder of the same version - if after all means to get it fixed have been exhausted.
Just today i've installed windows "14393.693" 23 times (all editions) and i didn't see any error messages.
after the updates, it's 14393.693 I no ran the DISM health restore commands. I'll clear my event log now and restart
After running the DISM Health / clean commands, the error disappeared while we're on the Event Log error topic, how to fix Event ID 10016: I've always had this error but never bothered fixing it
