If anyone has a similar problem with another program like VLC for example just enter the value of PlayWithVLC.
Hope this helps anyone as no solutions i tried on the internet worked.
To go in the reverse direction, open the drive in Explorer on double-click, you have to set that registry default value to blank. It took me months to find out how to set Open as default in Windows 7 instead of Play. I thought that was part of the tutorial How to Disable AutoPlay but it seems that tidbit is not there. There's an old post of mine before I found the same blank value you did.
