How do I stop my C drive appearing also as D on Windows 10 file explorer?

2

Am running Windows 10 Pro v1803. At some point a mysterious clone of my C drive showed up as D. This is an SSD. The drive letter doesn't appear in DISKPART. Nor does it show in Disk management console. I run as a regular user, and if I switch to another account on the machine, it doesn't appear. I have tried to remove the registry key for delegated folders, but that doesn't work. I have also tried the various options here: https://www.tenforums.com/tutorials/107032-remove-drive-letter-windows-10-a.html

My drives as shown in Explorer

D does appears in Disk Manager

Hmm what happens if you plug in an USB or something like that and assign the D letter to that (it should be free according to Disk Management) and then refresh the My PC view? – User025 – 2018-10-13T16:06:33.823

1In Disk Management, right click C: and choose Change Drive Letters... in the box that opens do you see D: listed as an assigned drive letter? – I say Reinstate Monica – 2018-10-13T17:31:06.197

In regedit check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\DOS Devices Is D: there? – Robert Andrzejuk – 2018-10-13T18:53:32.143

@RobertAndrzejuk. Nope, no D in there. – Kendor – 2018-10-13T19:18:10.520

@TwistyImpersonator No D in the drive letters. – Kendor – 2018-10-13T19:20:09.270

Deleting delegated folders is done under two keys, although I don't think that this is your problem:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\DelegateFolders
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\DelegateFolders

You could also start a Command Prompt (cmd) and enter the command :

subst D: /d

If successful, the virtual drive should disappear immediately. No need to restart Windows or anything.

I had tried both of those with no luck. The subst command doesn't recognize the D drive as being legit. – Kendor – 2018-10-13T17:24:32.807

Has this happened very recently? – harrymc – 2018-10-13T17:25:47.897

Last few weeks. – Kendor – 2018-10-13T19:21:59.983

If you still have a system restore point from a time that it worked, you may rollback to it. I would hate to advise you to do an In-place Upgrade because of such a problem - I would rather counsel ignoring this phantom.
