How to realize two users and one realtime PC?

Question

Windows

Hello, you need to make another desktop on the PC and give access via RDP or VNC so that the main user is not thrown out of the session.
Well, so that the sound is not transmitted.
How can this be implemented programmatically (preferably free software)?
Windows 7 system
And if possible, so that the remote user cannot view files on all drives except the system one (C:)

Answer 1

Here's how to do it all: 1) We take the patch from the link that Sergey
gave us in the comment 2) Computer (Properties) / Advanced settings / Remote access / Allow 3) Create a user with a password 4) On the desired disk, I have this drive D Properties / Security / Add user / and select / Deny "List the contents of the folder" 5) Delete the pppoe (or VPN) connection. We create it anew and indicate what is available to all users. 6) Check in the registry (If not, add a string parameter): [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon] "KeepRasConnections"="1" This is so that the connection does not break when connecting via RDP. Thanks again
Sergey for the patch and tips!
