How do I kill the popup graphics from the windows in my tray?

I have searched my computer & googled & just got to some very silly places.
These graphic popups giving me miniature versions of what my minimized windows look like, are driving me to distraction. I am assuming there is a way to disable this "facility?" Oh gawd I hope so.
Thanks to the saviour who will deliver me from this popup hell!
Seriously, thanks for being here!

Thanks for the instructions. However I have disabled Aero Peek & they are still popping up. I can no longer see my desktop when I point my cursor at the end of the tray, but I am still getting those huge thumbnails. I restarted too. Any other suggestions?

Yes. I edited my first post. I do apologize.
You will need to re enable aero peek and then follow the link in my first post.
Again I apologise for my mistake.

Yes I got there after you edited. The instructions there now, say to disable Aero Peek.

Here's a screenie - didn't know what size to put it so apologies in advance if needed. You shoud be able to see that Aero Peek is disabled but I'm still getting the thumbnai popups.
It will have to be an attachment, will that work?

I certainly did. Then I restarted. Then I went back to ensure it was still unchecked.
