When you hit alt tab on windows 7 and stop for a second on a window, it hides all other windows. Is there any way to tell Windows 7 to use the old classic behavior?

The fade is controlled by a timer and the timeout can be adjusted to any time period you want. Therefore, by extending the timeout to a longer period of time, you can effectively disable the fade. To make the change requires an edit to the registry.

Open your Registry Editor (regedit) and create the following registry key:


In that key, create the following DWORD value:


and set the value to the desired delay (in milliseconds) of when you want the fade to begin. Setting to something like 10,000 (decimal) will prevent the fade for a full 10 seconds.

NOTE: You'll have to restart Explorer to see the results....the easiest way to do that is logout and back in again or to reboot your machine.

Killing explorer.exe from Task Manager and relaunching it from there (File > Run) also works. Thank you, that was so annoying. – SilverSideDown Nov 1 '13 at 13:46

In Advanced System Settings (accessible from the System control panel), click the Advanced tab, then the settings button for Performance.

In the list of Visual Effects the following affects this behavior:

  • Enable Aero Peek

You will need to uncheck this, doing so will remove aero effects sadly enough, so it's either one.

This is not true. It is possible to (effectively) disable just the alt-tab functionality without loosing the whole aero effect. Please read and vote up the post by @Tall Jeff, who has provided a better answer. – Connor W May 5 '11 at 21:23
Also, if you would rather Windows 7 used the old alt-tab functionality, see the top answer from here:… – Connor W May 5 '11 at 21:25

The feature is called "Aero Peek". I was able to disable with:

Control Panel\All Control Panel Items\System\Advanced system settings\Performance
- disable Aero Peek

The solution to increase the timeout didn't work for me. It looks like the timeout maxes out at 3,000 milliseconds. See:

Disable or delay alt-tab Aero Peek effect in Windows 7

From the other superuser forum someone suggested VistaSwitcher. Just downloaded and installed it. Works perfect for me, nicer than the old Alt+Tab functionality and no timeout:

Funny that Johns URL ( mentions a different solution. In contrast to Tall Jeff who sets 10000 to LivePreview_ms, I set it to 0. And it worked. So, the complete solution was for me:

  • Open your Registry Editor (regedit) and create the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AltTab
  • Create a DWord Value LivePreview_ms
  • Set ValueData 0.
  • Restart the Explorer Service or the Computer.
