After configuring ProfileDisk and/or a User Data Disk, Users begin seeing unexpected drive letters in My Computer.
As part of Windows built in Autoplay functionality, Windows will automatically try to assign a drive letter to any new volume, which in this case are the new ProfileDisk and/or User Data Disks. While there are safeguards in place to try to prevent this, it is possible for Windows to assign drive letters before ProfileUnity is able to prevent it. To resolve this, you can disable Autoplay functionality via GPO:
Option 1) GPO
- Go to Computer Configuration\Administrative Templates\Windows Components\AutoPlay Policies
- Open ‘Turn Off Autoplay’ and set it to Enabled.
Option 2) Master Image:
- Go to KEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\
- Find the “NoDriveTypeAutoRun” entry and set a hexidecimal value of 000000FF. (If it doesn’t exist, you can create a new 32-bit DWORD with this name)
- Reboot computer.
Option 3) ProfileUnity configuration change:
- Go to ProfileUnity configuration
- Go to "Registry" create a new rule:
- Action: Add Value
- Hive: HKEY_CURRENT_USER
- Key: Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
- Type: REG_DWORD
- Value: NoDriveTypeAutoRun
- Data: 000000FF
