I still think this is most likely a bogus message which would properly indicate something else. FWIW I have recently devised a refinement for my script to list possible diagnostics
cd \
$This_Hour = Get-Date -Hour ((Get-Date).Hour -1)
LS -Re -Fi * -Fo -EA:SilentlyContinue | where LastWriteTime -GE $This_Hour | sort LastWriteTime | ft LastWriteTime, Length, FullName -AutoSize -Wrap
Also, there are Store- things in the Event Viewer which could provide some hints on their own (once they were enabled.)
Strangely only one of them is known by netsh trace but I think using netsh trace would be a way of getting more detail about what was going on network wise. Although we are limited in what we can collect
on RT I and even more limited on what we can do with what we collect I would be hopeful that there would be something that we could do with it on W10. E.g. I imagine being able to share the .etl files and use SysInternals strings program on them to at least
get whatever eyecatcher information that would be contained in them.
