Registry Key to Collapse Inactive Taskbar Icons

This article identifies the specific Windows Registry entry that controls whether inactive icons in the taskbar notification area (system tray) automatically collapse, and provides direct instructions on how to modify this setting using the Registry Editor (regedit).

The Registry Value

The registry entry responsible for automatically collapsing or hiding inactive taskbar icons is EnableAutoTray.

• Registry Path: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
• Value Name: EnableAutoTray
• Value Type: REG_DWORD (32-bit Value)
• Value Data:
  • 1 = Enabled (Inactive notification icons automatically collapse/hide into the overflow menu)
  • 0 = Disabled (All notification icons remain visible on the taskbar)

How to Modify the Setting

1. Press Win + R, type regedit, and press Enter to open the Registry Editor.

2. In the navigation bar or left sidebar, navigate to:

   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

3. Locate EnableAutoTray in the right-hand pane. If it does not exist, right-click on an empty space, select New > DWORD (32-bit) Value, and name it EnableAutoTray.

4. Double-click EnableAutoTray and set the Value data field:

   • Enter 0 to keep all icons always visible.
   • Enter 1 to allow Windows to collapse inactive icons automatically.

5. Click OK.

6. Restart the explorer.exe process via Task Manager or sign out and back into Windows for the changes to take effect.

Group Policy Alternative (Enterprise/System Enforcement)

If you need to enforce this behavior via policy keys, use the following entry:

• Registry Path: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
• Value Name: NoAutoTrayNotify
• Value Type: REG_DWORD
• Value Data:
  • 1 = Completely disables notification area icon hiding (forces all icons to display).
  • 0 = Allows user customization of tray icon behavior.
