Windows7 Aero Peek is the cool feature which makes every other window transparent while highlighting the thumbnail preview of an application window . This enables a clear view of the window which we want to take a look at. Clicking on a silver button at the bottom right corner of the window gives us a peek at the windows desktop making all other windows transparent and the gadgets which are free floating.
Pinning is the new feature which replaces the Quicklaunch . Now they are sided along with the open applications . All such applications pinned get a spot on the taskbar thus allowing easy access. All the running appplications has a glossy sheen over it and the rest remain dull . Adding of more than folder puts them under the Windoes explore icon and adding a file makes it associated with the application . So we actually have to use the jump list to select it.
