Enable/Disable Show Taskbar on All Displays in Windows 11 (7/17/2023 Updated)

Here's how to Enable/Disable Show Taskbar on All Displays in Windows 11.

Here are a couple ways to enable or disable showing the taskbar on all displays in Windows 11:

Using Registry Editor:

1. Open Registry Editor (regedit).
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced.
3. Create a new DWORD value named "TaskbarAl" (if it doesn't already exist).
4. To enable taskbar on all displays, set the Value data to 1.
5. To disable and show taskbar only on primary display, set Value data to 0.
6. Restart Explorer or reboot for change to take effect.

Using Command Prompt:

To Enable:
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v TaskbarAl /t REG_DWORD /d 1 /f

To Disable:
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v TaskbarAl /t REG_DWORD /d 0 /f

So in summary, setting the TaskbarAl value to 1 shows taskbar on all connected displays, while 0 restricts it to just the main display.

This worked for me using the description. I have the taskbar on my second monitor. However, the icons aren't there and my Taskbar settings doesn't have a "Multiple Displays" section to turn on taskbar icons for all displays. Any suggestions?

This TarkbarAI DWORD only changed the bar alignment for me. 0 left alignment and 1 center alignment
