Windows 10: Unmap or Disconnect Mapped Drive letter to a Local Folder

I have mapped Drive letter J: to a Local folder on my computer C:\Users\username\My Drive. I had to reset Windows 11 and may need to re link the J: to a new location. How do I unlink the mapped drive letter J: from this local folder so that it can be available again to map to a new location?Jay

Local folder mapped as Hard Disk Drive

I have a local folder on the C:\ drive that is somehow mapped as the T:\ drive. How do I 'unmap' this drive?

 

Local folder mapped as Hard Disk Drive

It could be a mapped or a substituted drive. These commands, when typed into the Run box, will tell you:

cmd /c net use & pause

cmd /c subst & pause

 

Unable to disconnect from mapped network drive

I receive the following error when I try to disconnect from a self mapped network drive: "network connection does not exist"

The network drive icon appears with a bid red x and says it is disconnected, yet I can double click on it to enter the mapped folder. Doing this does not reconnect the folder, and remains disconnected. This causes problems because programs that pointed
to this path are unable to read the files. I am unable to remap this drive because the associated drive letter (E and mapping no longer shows up in the list.

I've tried all the typical suggestions including:

--I tried to do it via the command prompt with the net use delete command, but it can't be found in there.

--Tried to above with the actual network path instead of the drive letter, did not work

--Tried to delete the registry entries from:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2

HKEY_USERS\. Default\Software\Microsoft\Windows\CurrentVersion\Explorer\Mountpoint2\

None of these solutions worked. Though deleting the registry entries momentarily hid the disconnected drive, the drive letter was still not available for mapping. I tried to force the drive letter (E to map to my optical drive, which worryingly, pointed
back to the mapped network location on the NAS instead of to the optical drive.

How do I get rid of this? Reformatting the computer is not an option.
