Aero Peek pre Win7?
Are you running Windows XP or Vista, and in need of the AeroPeek feature in Windows 7? Yes, you could download one of many AeroPeek clones for Vista or XP and be a happy camper, but what if you don’t want any more software on your speedy PC?
It turns out Windows XP and Vista have a hidden shortcut that provides a similar behavior. While clicking and holding on the title bar of any window you are moving, press the ESC key and it will return to where it was originally placed! It’s that easy, no hacking required.
