Dual drives listed in "File Explorer"

Have my drives listed twice in this new build, ver. 1703, OS.Build-15063.296.
Had a little program downloaded from Ten Forums which dealt with this problem, just had to run it and it took care of the problem, however it won't work in this new build.
I know it has to do with the registry, the problem is I have no idea where to find the key and what the key should be set to to get rid of the problem. Can anyone point me in the right direction and tell me what the key should be set to?
Thanks in advance.

Hello Brink;

I have to say that it's rather interesting that you should list that specific tutorial as I had the same problem originally when Win 10 first came out. I had posted the same problem as was directed to the same tutorial, at which time I had downloaded the same fixes. Funny that the copy I had would not work after the last update and after downloading the fix again, it worked, no more double drives.
I appreciate your help and will definitely bookmark that tutorial just in case.
Guess I'll just mark this as solved.
