Regedit Value for Classic Volume Mixer in Windows

Windows allows users to switch between the modern volume flyout panel and the classic volume control interface by modifying a specific value in the Windows Registry. This article explains the exact registry path, the specific DWORD value responsible for controlling the volume mixer’s visibility (EnableMtcUvc), and the step-by-step process to apply these changes.

The Registry Key and Value

The visibility of the classic volume control versus the modern interface is controlled by the following registry entry:

• Registry Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MTCUVC
• Value Name: EnableMtcUvc
• Value Type: REG_DWORD (32-bit Value)
• Value Data:
  • 0 = Enables the Classic Volume Mixer
  • 1 = Enables the Modern Volume Control Panel (Default)

How to Change the Volume Panel in Registry Editor

1. Press Windows Key + R to open the Run dialog box.

2. Type regedit and press Enter to launch the Registry Editor.

3. Navigate to the following key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

4. Check if a subkey named MTCUVC exists under CurrentVersion.

   • If it does not exist, right-click CurrentVersion, select New > Key, and name it MTCUVC.

5. Select the MTCUVC key. In the right pane, look for the EnableMtcUvc value.

   • If it does not exist, right-click the empty space, select New > DWORD (32-bit) Value, and name it EnableMtcUvc.

6. Double-click EnableMtcUvc and set its Value data:

   • Set to 0 to switch to the classic volume interface.
