i'm using subst to create virtual drive mapping to a working folder for ease of use (i can't use mklink as "secpol.msc" is disabled, or new-symlink as power script is disabled), the Volume of the virtual drive is set the same as the physical drive where the working folder belongs to. Is there a way to change the Volume of the virtual drive?
As you suspected, Mount-Points always share the name of the root drive they are located on. Renaming often renames both. Apparently the registry can be temporarily modified if that suits your need.
A quick alternate could be NET USE. At least this takes the label of the folder you are mounting instead.
Ps. NET USE must point to a network share eg:
NET USE v: '\\localhost\c$\Temp'
^^ This will create a new
V:\ drive called
Temp ... assuming this folder exists (and the administrative share is available).
