Hi Damian
I am Dave, I will help you with this.
Microsoft deliberately disabled Autorun.inf files because that was a major way that malware was spreading form PC to PC, when users inserted a CD, or USB drive into a PC.
Open the old Control Panel, at the top right of the old Control Panel, set View to icons
Open Autoplay, then scroll down to the 'Software and Games option, set that to 'Install or run a program form your media'
Save that setting, then restart (not shut down) your PC
Check if your Autorun file will run when you insert the disk, if not, they must have that totally disabled now in Windows.
