Is there any way to get rid of the taskbar thumbnail previews on Windows 7 once and for all?

Snip from reference below (Edit: THIS APPEARS TO ONLY WORK FOR Vista): How to Enable or Disable Taskbar Thumbnail Preview in Windows 7

  1. Click on Start button and type GPEdit.msc in Instant Search text box, then hit Enter.
  2. Navigate to User Configuration -> Administrative Templates -> Start Menu and Taskbar in left pane of Local Group Policy Editor.
  3. Locate and double click on Turn off taskbar thumbnails in right pane of Local Group Policy editor.
  4. Select Enabled radion button.
  5. Click OK to make the change effective.
  6. Logoff and logon again or restart computer if needed.

Edit: For Windows 7:

  1. Backup registry
  2. Win + R -> regedit
  3. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband
  4. Right Click Taskband folder -> New -> DWORD 32-bit value
  5. Name the new DWORD MaxThumbSizePx
  6. Right click the new DWORD -> Modify -> enter "1"
  7. Reboot

I've tried this method with out luck, I don't really know what the cause is. – Oily Jun 14 '13 at 18:34
@Oily Looks like it's going to require a registry edit. Interested in that as an alternate answer? – panhandel Jun 14 '13 at 18:46
yes please.................................... – Oily Jun 14 '13 at 18:48
@Oily ok, check edit. This is as good as it appears to get without disabling the aero theme. – panhandel Jun 14 '13 at 19:10

If nothing else helps 7+ Taskbar Tweaker will for sure:


You'll need to keep it running, but it's quite a light-weight app and a portable installation is possible.

the bad thing about this is that it needs to be running – Oily Jun 17 '13 at 17:30
Yes, I already mentioned that clearly. However I find it so useful that I don't really mind, and it's not too heavy. I love the latest feature that's been added to display seconds in the tray clock. You can see other ways to use it from my previous answers. – Karan Jun 17 '13 at 17:35

If you mean that you want to disable the Aero Peek feature (Where you see the preview of whatever the running task is when you hover your cursor over it), these are the best instructions I've found:

Strangely, unchecking only "Enable Aero Peek" and even logging off and logging back in or restarting did nothing for me on Win7, since the thumbnail previews still show up. – Karan Jun 14 '13 at 23:58

The best solution I have found is to go into this registry key:


Then create a new DWORD value called ExtendedUIHoverTime with a value of 20000. That's supposed to cause a 20 second delay before the preview pops up, but for me it stopped it from happening entirely.
