Windows – Disable Access to Drives for Limited Users in Windows

Authenticated Users is a pseudo-group (which is why it exists, but is not listed in Users & groups), it includes both Local PC users and Domain users as explained in this Technet article

In Windows Vista and later you can apply policies only to a specific account, but you have to load the group policy object editor from the Microsoft Management Console, not by opening the snapin directly.

1. Open mmc.exe
2. When the MMC console opens, click "File" -> "Add/remove snapin"
3. Select "Group Policy Object Editor" and click the "Add >" button
4. In the dialog which appears, click "Browse".

5. Click the "users" tab and select a user.

   

6. Click "OK", then "Finish", then "OK" again

You will now have a group policy user object for the selected user. Apply whatever restrictions you want. You may be interested in checking out "Hide these specified drives in My Computer" in User Configuration > Administrative Templates > Windows Components > Windows Explorer.
