    Hi Cliff!

    Thank you for this Information!
    You're welcome. But That's one place I personally leave alone, as much as I play around in the registry.

    That is odd, All mine in use show up, and the USB stick(F) that I once in a while use is also there under DOS devices.

    What the devices that look like this-->"\\??\\Volume{fae10e38-61ce-11e5-9c22-c03fd53709f0}"= are, I have no idea what they are. I suppose they are the hidden partitions like Recovery, EFI, Unallocated(for my SSD), and the System Volume Information(a kind of index for the drive where on disk everything is).

    you should have at least 6 \??\Volume{ for every partitions and if you plug a usb stick or usb hard drive or a dvd burner
    i know it's very odd
    did you perform a fresh w10 installation ?
    thanks Cliff

    ps. i tried to delete the \\??\\ keys because at the boot windows should generate them , but i have only 1
