I upgraded from W7 to W10 and, so far, have not had any major problems. However, I have noticed that during
the WIndows start-up cycle my DVD drives are being accessed, causing them to grind unnecessarily and delaying
the start-up. This wasn't happening with W7. It would boot right up from the SSD system drive.

Is anyone seeing this behavior? Is there a way to stop the drives from being accessed/scanned during the boot cycle?

I'm using Comodo for the firewall and Avast for virus protection. The BIOS is set to boot from the SSD as the primary,
with no other drives specified.

Any ideas or suggestions would be much appreciated.
