How to Change Alt-Tab Behavior in Windows Registry

The behavior and appearance of the Windows Alt-Tab window switcher can be modified directly using the Windows Registry Editor (Regedit). By adjusting specific DWORD values—most notably AltTabSettings and MultiTaskingAltTabFilter—you can switch between the modern thumbnail preview interface, the classic legacy icon switcher, or manage how Microsoft Edge browser tabs appear in the multitasking menu.

The Primary Value: AltTabSettings

The main registry value responsible for altering the visual layout and behavior of the Alt-Tab switcher is AltTabSettings.

• Registry Path: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
• Value Name: AltTabSettings
• Value Type: REG_DWORD (DWORD 32-bit Value)
• Value Data:
  • 1 = Enables the classic, lightweight Alt-Tab switcher (resembling the Windows XP/legacy icon grid).
  • 0 = Enables the modern Alt-Tab switcher with window previews and thumbnails (Windows default).

How to Modify AltTabSettings in Regedit

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

2. Navigate to the following key:

   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

3. Look for the AltTabSettings value in the right pane. If it does not exist, right-click an empty area, choose New > DWORD (32-bit) Value, and name it AltTabSettings.

4. Double-click AltTabSettings, set the Value data to 1 to use the classic switcher (or 0 to keep the modern layout), and click OK.

5. Restart Windows Explorer through Task Manager or sign out and sign back in to apply the changes.

Controlling Browser Tabs: MultiTaskingAltTabFilter

In Windows 10 and Windows 11, the Alt-Tab switcher includes tabs from Microsoft Edge by default. You can control this specific behavior using the MultiTaskingAltTabFilter registry key.

• Registry Path: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
• Value Name: MultiTaskingAltTabFilter
• Value Type: REG_DWORD (DWORD 32-bit Value)
• Value Data:
  • 3 = Open windows only (disables Edge tabs in Alt-Tab).
  • 2 = Open windows and the 5 most recent tabs in Edge.
  • 1 = Open windows and the 3 most recent tabs in Edge.
  • 0 = Open windows and all tabs in Edge.

Setting MultiTaskingAltTabFilter to 3 provides a clean Alt-Tab view containing only running applications without individual browser tabs cluttering the interface.
