In Windows Vista & 7, Winkey+Tab, switch to various programs by Win-flip [A 3D Experienced Switching], Whereas in Windows Xp and earlier versions It just points the program, whether to restore,minimize,maximize, etc through keyboard. Alt+Tab, also does the same thing in Windows 7 and Vista without Win-flip. In Xp and previous versions Classical Windows Switcher appears.
ACTUAL ANSWER: Both gives option to switch between running Programs.
CTRL+ALT+TAB on most windows 7 machines stays even when you stop pressing key and wait for confirmation of windows selection. ALT+TAB switches instantly and is not waiting for confirm (mouse click on icon or RETURN key);
Alt+Tab is a hotkey for switching between windows such as Internet Explorer to another program such as Microsoft Office Word.
Alt Tab is a more basic way of changing from one task to another, the Windows + Tab gives a preview of the task you are potentially going to change to, you can select other tasks, by holding the windows key whilst tapping the Tab key
The CTRL key is the only difference. What it actually does depends on the currently active program and/or control, and whether or not the key combo has been implemented or not. If not, the shell processes the key combo. On my system (Windows 7), both combos bring up the task switcher.
When the Alt Key and the Windows Logo Key are pressed simultaneously, a window in the center of the screen will appear, and while holding down the Windows Key and pressing the Alt key, you will switch between Applications that are open and the Desktop.
You can Hold the Alt key while pressing tab (Alt+Tab) to flip through the running windows.
