Problem

Aero Peek is a nice feature generally but I find it very annoying during Alt+Tabbing (peek windows hiding the switch dialog, it doesn't really work on multiple monitors etc.). Is there a way to disable Aero Peek only during the Alt+Tab operation? I don't want to turn it off globally.

Disable Aero Peek During Alt+Tab Operation

Medium Risk

Aero Peek is a Windows feature that allows users to preview open windows by hovering over their taskbar icons. During the Alt+Tab operation, this feature can interfere with the visibility of the window switcher, especially on multi-monitor setups, as it may display previews that obscure the Alt+Tab dialog. Unfortunately, Windows does not provide a built-in option to disable Aero Peek specifically during Alt+Tab, but we can achieve a workaround using registry settings and a script.

Awaiting Verification

  1. 1

    Create a Registry Backup

    Before making changes to the Windows Registry, it's crucial to create a backup. This allows you to restore the original settings if something goes wrong.

    bash
    reg export HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced C:\Backup\AeroPeekBackup.reg
  2. 2

    Modify Registry for Aero Peek

    Change the registry setting that controls Aero Peek. This setting will disable Aero Peek temporarily during Alt+Tab operations.

    bash
    reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v EnableAeroPeek /t REG_DWORD /d 0 /f
  3. 3

    Create a Script to Toggle Aero Peek

    Create a script that toggles Aero Peek on and off. This script will allow you to disable Aero Peek before using Alt+Tab and re-enable it afterward.

    bash
    echo "reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v EnableAeroPeek /t REG_DWORD /d 0 /f && timeout /t 1 && reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v EnableAeroPeek /t REG_DWORD /d 1 /f" > C:\ToggleAeroPeek.bat
  4. 4

    Run the Script Before Alt+Tab

    Whenever you want to use Alt+Tab, run the created script (C:\ToggleAeroPeek.bat) to disable Aero Peek. After switching windows, the script will automatically re-enable Aero Peek.

    bash
    C:\ToggleAeroPeek.bat

Validation

To confirm the fix worked, perform an Alt+Tab operation after running the script. The Aero Peek feature should be disabled, allowing for a clear view of the Alt+Tab dialog. Check the registry setting to ensure it has reverted back to enabled after the operation.
