Windows 10 doesn't recognize subst drive letters in Explorer

Subst seems to be broken in Windows 10.

Windows 10 Pro

Version 20H2

Build 19042.421

When using subst to create a new drive letter, the new drive is available in the command prompt, but the drive letter does not show up in Explorer, even when I run the subst from an elevated command prompt. Previously, the subst drive letter would appear in
Explorer.

Please don't tell me to run "sfc /scannow". We all know to do that. It doesn't help.

This would happen if you ran the subst command in a different account context than File Explorer.

 

Reformatting - Wrong Drive Letters?

Ok, do so googling about acronis True Image 11 and disk letters. Its the program I use to save all my info, and I know that people wee having troubles with the drive letters there. It was something about modifying the boot.ini and assigning drives. Anyway, I found this for you:

Change the System/Boot Drive Letter
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

1. Make a full system backup of the computer and system state.
2. Log on as an Administrator.
3. Start Regedt32.exe.
4. Go to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
5. Click MountedDevices.
6. On the Security menu, click Permissions.
7. Verify that Administrators have full control. Change this back when you are finished with these steps.
8. Quit Regedt32.exe, and then start Regedit.exe.
9. Locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
10. Find the drive letter you want to change to (new). Look for "\DosDevices\C:".
11. Right-click \DosDevices\C:, and then click Rename.

Note You must use Regedit instead of Regedt32 to rename this registry key.
12. Rename it to an unused drive letter "\DosDevices\Z:".

This frees up drive letter C.
13. Find the drive letter you want changed. Look for "\DosDevices\D:".
14. Right-click \DosDevices\D:, and then click Rename.
15. Rename it to the appropriate (new) drive letter "\DosDevices\C:".
16. Click the value for \DosDevices\Z:, click Rename, and then name it back to "\DosDevices\D:".
17. Quit Regedit, and then start Regedt32.
18. Change the permissions back to the previous setting for Administrators (this should probably be Read Only).
19. Restart the computer.
