How To Disable Taskbar Thumbnail Preview in Windows 7

Windows 7 does not include a GUI to disable the taskbar thumbnail preview feature. I’ve experimented with the registry setting TaskbarNoThumbnail and its equivalent GPO Turn off taskbar thumbnails. That setting seems to apply only to Windows Vista, and has no effect in Windows 7.

You can however disable the taskbar thumbnail feature (sort of) in Windows 7 using a registry edit. This can be done by setting the taskbar thumbnail preview hover delay to a large value (say 10000 milliseconds or more), so that the preview is not immediately generated when you hover over a taskbar icon. Well. Then the article title should have really been "How To Delay Taskbar Thumbnail Preview in Windows 7".

I heard about this registry value via article Adjust Taskbar Preview Hover Delay at WinGeek.com (Credits to Steve Sinchak), and experimented the registry value by inputting a large decimal value to prevent immediate display of thumbnails in the Windows 7 Taskbar.

1. Click Start, type Regedit.exe and press {ENTER}

2. Navigate to the following location:

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced

3. Create a new DWORD (32-bit) value named ExtendedUIHoverTime

4. Double-click ExtendedUIHoverTime and click Decimal

5. To increase the hover delay to 5 seconds, type 5000. Type 10000 for 10 seconds and so forth…

6. Exit the Registry Editor.

7. Logoff and login back, or restart the Shell ("Exit Explorer" method).

  1. I am looking for an EASY way to remove these pesky thumbnails — it seems like there ought to be a very simple way to remove them. It was surely easy enough (so it seems) to add them in … I just want them GONE, for GOOD. I am not a fan of dinking around in the Registry, though I have in the past and probably will again.

  2. There is a way to get rid of the thumbnail previews for good but i cant remember how do it. I did it when i first got windows when i was fiddling with windows 7 without going into REG EDIT or anything like that but i cant remember how to do it again. I f**ked it up when i was playing wiith the desk top so it can be done. Good Luck.

  3. right click on computer > advanced system settings > advanced tab > performance settings > uncheck/check ‘enable desktop composition’

    This will disable/enable preview of windows on the taskbar.

    Um, not to be completely ludite, but… how?
    I know that I can really foul up regedit if i do this wrong, so a bit more hand-holding would be appreciated, please.

  5. Does not work for me at all on windows 7… why isn’t there an easy way to fix this extremely annoying feature???

  6. Ramesh,

    I have been doing extensive search for this issue and your resolution was the only thing that actually worked!!!
    Thank you thank you !!

  7. It worked. It’s just that I set it to 10,000 and now it takes ~1 and 5 secs to show up, not 10 seconds.

    For me it’s find, I don’t want that feature

  8. I tried it with Windows 7 Home Premium and ExtendedUIHoverTime was already in the registry. I changed its value to 10000 decimal and at first it seemed to have no effect. However, I then logged off and re-logged on and now the popups seem to have stopped.
