如何将Alt+Tab的窗口预览行为恢复为仅显示应用图标？

Alright, let's fix that Alt+Tab behavior so you get back the classic icon-only view instead of those overlay previews. Here's how to do it depending on your Windows version:

Windows 11 doesn't have a built-in setting to switch back to the classic icon-only Alt+Tab, but we can use the Registry Editor to make the change:

• Press Win + R to open the Run dialog, type regedit and hit Enter (click "Yes" if the User Account Control prompt pops up)
• Navigate to this registry key using the left sidebar:

  HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
  

• Right-click on the Explorer key > select New > DWORD (32-bit) Value
• Name this new value AltTabSettings
• Double-click AltTabSettings, set the Value data to 1 (make sure the Base is set to Decimal)
• Save the change, then either restart your PC or restart File Explorer:
  • Right-click the taskbar > select Task Manager
  • Find "Windows Explorer" in the list, right-click it > select Restart

You can either use the Settings app or the Registry method (same as above):

Option 1: Via Settings #

• Open Settings with Win + I
• Go to System > Multitasking
• Scroll down to the "Alt + Tab" section
• Use the dropdown menu to select Open windows only (this reduces preview size; for strict classic icon-only view, use the Registry method below)

Option 2: Registry Method #

Follow the exact same steps listed for Windows 11 above—setting AltTabSettings to 1 will force the classic icon-only Alt+Tab view.

A quick note: If you have any third-party window management tools installed (like PowerToys or similar), they might override this system setting. Double-check their preferences if the above methods don't work.
