I'm happy to say that two OLD games no longer seem to crash!
This is actually a sort of 'biggie' for me as the game crash sometimes caused an issue with Office Outlook to where I would have to do a repair of Office to recover if I forgot to close Outlook before starting either game. Of course I can't actually know but this seems to point to the possibility of the diagnostics telemetry actually being a good thing. I have quit shutting down Outlook before opening either game.
I run a rather heavily 'tweaked' version of Windows 10. Most of these tweaks deal with appearance and performance DID suffer a bit. Since the upgrade to the newest Windows 10 version such 'lags' in performance seem to be gone.
Bottom line is that I seem to be happy with the 4/17 'Creator's build' upgrade.
