There is no way to properly disable aero peek for just alt-tab, but you can set the delay to an absurdly high value, effectively disabling it. There is another post detailing this process. Essentially, you need to create the DWORD value LivePreview_ms in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AltTab to a very large number. This key stores the time in milliseconds to delay, so 60000 ought to be enough, since I doubt you hold alt-tab for more than a minute.
Even though the peek button is located at the extreme right on the taskbar, the button is easily visible in Windows 7 unlike in the later versions of Windows. In Windows 8 and Windows 10, you just need to move the cursor to the bottom right-corner of the desktop in order to peek through all open windows.
Windows 7 introduced a new handy feature called "Aero Peek", that allows you to, well, peek at your desktop to see its content, without having to minimize any window. This feature is useful, but can also get in the way. We'll start this tutorial by explaining what Aero Peek is, and finish by showing you how to disable Aero Peek (and how to re-enable it of course), and by showing you alternatives to Aero Peek if you have disabled it. You will also learn an easy fix for the most commonly asked about "Aero Peek doesn't work" problem - simple and obvious once you know the answer.
To show your desktop when Aero Peek is disabled, hold down the Windows logo key, and press "D" (as in Desktop) - Windows will minimize all windows, and let you peek at your desktop icons and files. To bring back all windows you had showing, simply press Windows+D again. Unlike the Windows+M keyboard shortcut, which minimizes windows, but doesn't bring them back up, the Windows+D keystroke is a full replacement to Aero Peek (without nice animation or transparency though!)
Aero Peek is a latest feature in Windows 7 operating system enables us to quickly transfer your control on the desktop area without clicking on minimize button of all opened windows. When you take your mouse pointer on the show desktop button which is located on the extreme right corner of your taskbar, all active program windows are become transparent or convert in an icon and placed in the taskbar, to quickly allow you to watch the desktop items. You can also easily disable aero peek feature. We are talking about AERO-PEEK feature in Windows 7.

As first seen in Windows 7, thumbnail previews let you have a peek on the tasks on your taskbar. By hovering the mouse on a task on the taskbar, a thumbnail preview pops up and shows what is running on the selected application. The hover time is predefined, and the default is set to half a second. By hovering on the thumbnail that pops up, you can be able to sneak a peek of what is running on task window without actually going to the task. This has been a handy feature that lets you view tasks easily and still get to your current task easily.
