Windows 8 vs Windows 7
a) Windows 8 is a much bigger bet for the company since over a billion people use Windows. The first most visible difference is that the Start button which first appeared in Windows 95 and persisted in each new Windows version, is now gone. Instead, there's a hot bottom-left corner of the screen to reveal the hidden Start button.
b) At the same time, the Start menu has also gone making way for a full screen interface called the Start screen that uses dynamic tiles instead of static computer icons. It's accessible as a hotspot in the lower left corner of the screen.
c) The Metro-style theme has replaced the Aero Glass theme, the graphical centerpiece of Windows Vista and Windows 7.
d) Microsoft has removed its no-so-popular feature called Flip 3D, which is used for windows switching (WinKey+Tab). Instead now users will see a Modern UI app switcher, which can be accessed with the movement of the mouse.
e) Popular desktop widgets like Clock, Currency Conversion, Calendar, Feed Headlines, Notes, Stocks, Weather, etc. will not be visible as a part of Windows sidebar. However, users can access them through the Start Screen.
f) All Windows-Update-related messages will now be shown on the login and lock screens.
g) To view the recent documents use Search in Charms bar to find any documents on your Windows 8 PC.
