Hi, frustratingly, the upgrade sets all default settings (there are many) to default, and autoplay off.

These steps are necessary (in my experience).

1. Follow this old fix:
Fixes for AutoPlay Dialog Box Not Appearing When Plugging in a Removable Device • Raymond.CC
2. Enable Autoplay in Settings, remembering there are many more configuration options in Control Panel, Autoplay.
3. Add a script to poll your CD/DVD drive.

(Previously I found this was the only way to get autoplay to work with this in Win 10).

Improvements in the Anniversary Edition:
1. Autoplay also now works for flash drives (previously for me it worked for external USB HDDs, not flash drives)
