I assume you mean the taskbar thumbs.
It requires a registry edit if you are confident enough to mess with registry settings.
Open regedit.exe and navigate to
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
There should be a d word value in the right hand side named
TaskbarNoThumbnail
set its value to 1 to turn off thumbnail previews. Reset to 0 to re-enable thumb nail previews.
A registry (.reg) file to turn off thumbs should look like this
Quote:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"TaskbarNoThumbnail"=dword:00000001
And to turn them back on
Quote:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"TaskbarNoThumbnail"=dword:00000000

OOOPS!! I suppose I should have really mentioned I only use these registry edits when I'm busy in Photoshop.
