( not sure If I have the right forum) ..

Up to today my windows 10 always allowed an inserted DVD or blueray disc to automatically open up my powerdvd17 software and play the disc back on my desktop in the right software automatically .. now it won't open to playback..

I have to do one of two things either click the desktop icon to recognize and playback ..

or open up explorer and find the right drive and right click play from there ...

Why won't it open and playback on auto ... by itself? what settings has to re applied? to the drive or the software?

Ideas ???
