How to change the letter of the system drive C:\ in windows server 2008 or make the client drive available in the rdp session along the c:\ path?

Question

System administration

Due to the need to run a bunch of users with very crooked software, there is a need for the user's C:\ drive to be available on the terminal (2008R2) in the user session along the c:\ path (otherwise there is a wagon of conflicts, the software writes user information to c:\blablabla and not in the user's profile). The problem is solved by changing the letter of the system drive, but I already managed to forget how to do it, this question is still somehow hard to google (in the context of 2008).
Please, suddenly someone remembers or who has a link at hand?
Or maybe there is a more elegant solution to the described problem?

Answer 1

everything, I remembered. still, without reinstalling the system, there is no way, but first the drive letter changes in the registry in the MountedDevices branch - after rebooting, we get a dead Windows, on top of which you can install the normal version.

Answer 2

My computer-management-disk management-change label (or something like that)

Answer 3

You can create a hardlink of the user profile from the system drive to the C drive :)) Or, if the program is stupid and does not work with system variables, try to find the program configs and change the paths there (and such things are often contained in some ini files)
