Here is an overview of the differences between Windows 7 and Windows 8:
- Faster Start Up Mode. Windows operating systems have always taken a long time to start up. Windows 8 starts much faster thanks to a new feature that functions like a cross between hibernation and cold boot.
- Improved Windows Explorer. The ribbon interface that was introduced in MS Word 2007 and 2010 is now also the default Windows Explorer UI. New buttons on the UI for managing files are a welcomed improvement.
- Simpler Task Manager. See applications running in your PC in a more visual Task Manager. Applications are highlighted with a heat map showing the extent of PC resources each is using.
- No Start Button. The Start button is hidden by default in Windows 8. Instead, an Metro UI featuring commonly used applications has replaced the Start button, giving Windows 8 a smartphone UI look.
- Improved Copy, Move, Rename and Delete. With Windows 8, you can now copy or move multiple files and see the progress in a single dialog box. Moreover, you can pause and resume copying or moving files.
- Plugin Free Browsing. We are familiar with the occasional message requiring a plugin when trying to access a certain type of content. IE 10 supports HTML 5, which supports viewing many content types without plugins.
- ARM Support. Perhaps the notable technical difference in Windows 8 is its support for devices running on ARM Architecture. Traditionally, Windows has only supported AMD and x86-based Intel PCs. ARM chip architecture is increasingly being used on different devices and Microsoft is keen to have Windows 8 running on the devices.
