I like the windows 7 grouping behaviour for multiple similar windows, except when I have multiple Explorer windows open. In this case, showing thumbnails of each open explorer window is next to useless, and I would like to know how to either:

• Disable thumbnail display completely (but preserve the grouping behaviour)
• Disable thumbnail display for a subset of programs (all explorer.exe instances)
• Change the number of similar programs that are open before the grouping behaviour falls back on a more sensible text preview when hovering over the taskbar icon (currently 14 or over)

I don't particularly want to disable any other features of windows to get this behaviour, so disabling the theme compleletely isn't what I want to do. I definitely want to keep the grouping behaviour. Its just those thumbnail previews I would like to alter.

Here are some screen shots of what I don't want, and what I do want:
