Honest speaking Windows 7 is almost similar to Vista. Indeed, most of what gets us hot and not so bothered about is what's on top: If we talk about look and feel, the new GUI is the largest step forward since Windows 95. The cool taskbar is our favorite new UI element of Windows 7 It's the largest change from Windows past, and in our view, the best. But it may result in some confusion initially because it groups programs that are open and those that are not into one big party the theory is that it should not matter if it's already running or not if you would like to open it.
That might kind of remind you of OS X's Dock, but it works a bit differently and definitely still operates on the Windows paradigm. Together with Aero Peek, which makes every window on the desktop transparent except the one you're highlighting at the moment, you can search any window nearly instantly, no matter how many windows your desktop is buried under.
In applications coded to take advantage of the jump list, when you right-click an icon, you'll see a pop-up menu where you can quickly choose common functions. In Internet Explorer, it displays your recent browsing web pages; in Windows Media Player, it'll let you play recent videos; and Windows Explorer will give you quick access to pinned and frequently open folders and files. Expect jump lists to be more useful as new applications are released for Windows 7 that build functions into the Jump list.
Gone is the Quick Launch bar, where you used to keep shortcut buttons to your favorite programs. Now they just hang out on the taskbar with open applications. When you "pin" something, like an applications or folder, it's got a permanent place on the taskbar for easy access. When the applications is running or the folder is open, the icon has a glossy sheen over it. One quirk with folders: If you try to pin more than one to the taskbar, they're all collapsed into a single Windows Explorer icon. Also, if you pin a file to the taskbar, it's actually pinned to the icon of the program that opens it, so you'll have to right-click that icon to pop up the jump list and select it from there.
Frankly speaking, Windows 7's is not too different from the Windows you've known and loved for years. It just got a handy new UI features scattered through that make it easier than ever to multi-task with Windows, with the side effect of making it look modern and kinda neat, too. Gadgets, widgets, whatever you want to call them, they're little mini programs strewn across your desktop that perform useful things like weather report. In Windows Vista they were like little ducks in a row, sitting on the sidebar by default, but now they're free floating on your desktop, where they're more useful.
