Tiny little boxes

OK, I was out downloading files, for a video game) and the spiffy dialog
window kept popping up and asking if I wish to create a folder.
In the far corner was a tiny box asking if I wish to turn off this window in
the future.
Now I want it back on, and have no clue how to find one tiny little box
again...

Ah, regrets...How thin my memories would be without them...

Hello, there must be a fast and easy way, but I only know one - system restore. Choose a date before you turned off that window as your restore point. Hope you'll have your tiny box back.
