  9. 9. DEVELOPMENT & PLATFORMS Windows 8 represents a reimagining of Windows from the chipset to the experience. Since this is a week focused on developers, we also detailed the boldof the re-imagination of he Windows platform, tools, and APIs We will show the brand new tools that allow you to code Metro style applications in HTML5/JavaScript, C/C++, and/or C#/XAML. Metro is an internal code name for a typographybased design language created byMicrosoft, originally for use in Windows Phone 7. Early uses of the Metro principles, such as the typography, began as early as Microsoft Windows 8. "Metro" is based on the design principles of classic Swiss graphic design.

  11. 11. Windows Boot performance Few days back, we got a new feature of high booting capability of Windows 8 OS. According to this feature, Windows 8 fine tuning with start-up process will going to increase its popularity because many users want fast booting speed. Windows file system Windows 8 provides strong file system support which cannot allow unauthorized users to make changes in Windows secure files. As it implements more security for file accessing. A new feature of "file name collisions will be there in Windows 8 so as to avoid redundancy of same file in system memory.

Windows 8 that enables enterprise administrators to create USB drives containing complete, managed Windows images that users can use to boot and run. Windows 8 Start Screen – The Start screen is yet another impressive. The screen basically groups all your applications together, which you can easily drag and drop, or add new things.
  13. 13. Charms In large part, "charms" is a new implementation of the traditional Windows start bar. Charms can also be used to quickly configure settings for individual apps. On an ordinary non-touch PC, charms are accessed by dragging the mouse to the bottom-left corner of the screen, to the same spot as the old Windows start button. On a tablet, you swipe from the right side of the screen to bring up charms. Microsoft recently applied for a trademark on charms. The charms sidebar offers five sets of options, supporting both app-specific settings and system settings such as volume and brightness. The options include Start, Search, Share, Devices, and Settings. The Start option returns the user to the home screen. The Devices option presents a list of connected devices. Under the Share option, users can see social network sharing apps.
  14. 14. Snap Multi-tasking "Snap multitasking" is designed to make it easy to run two apps in Windows 8 side-by-side, to resize them, and to switch between them. On the righthand side of the screen, you can snap an app into place. You can make an app smaller or larger by dragging the bar for the app. To switch between apps in Windows 8, you swipe from the left-hand part of the screen. However, Windows 8 does not allow you to view all of your running apps on a single screen
  15. 15. Some more INTRESTING FEATURES OF WINDOWS-8 UEFI we all know the BIOS (basic input output System) from the day we have known Windows .BIOS is generally used when we mess up with the windows and not very often. The drawback of BIOS is that it is not very user freindly. The Unified Extensible Firmware Interface (UEFI) is a replacement for the BIOS. It reduce boot time and also secure the Pc during the boot time with the trusted boot feature. UEFI lso allows diagnostics to be performed on the boot screen over the network.

  21. 21. WEEKNESS OF WINDOWS -8 OS 1. Very difficult to move between screens Metro Switching between applications is a very difficult thing to do. You are not given functions such as Alt-Tab while working with the desktop and the keyboard to switch from one app to another app. Instead, in Windows 9 Metro could could use a pointer or finder. Put on the left side of the screen and drag. Or click on the icon that appears. 2. Metro multitasking = 2 application only If you use a Metro application (for tablets) in Windows 8, multitasking means the screen will display two applications in a row. That's it. For beginners it would not be a big problem. However for the advanced user, multitasking capabilities with Metro for only two applications is a fatal weakness. 3. There is no option to turn tiles into icons The smallest size is still too large tiles appearance. When will you have to install many applications will show screen Metro.
  22. 22. Featured Research Windows 8 is now available, but most organizations are still deploying Windows 7 and working to eliminate Windows XP by the time support ends in April 2014. Organizations need to decide how much time to spend on Windows 8, and which users to target with the new OS. Windows 8 will be well-received by users with tablets, convertibles, hybrids and other devices with good touch support. Windows 8 tablets can offer the IT organization enterprise manageability; however, the shift is likely to require additional investment in training, application porting and tool upgrades. Windows 8 includes new features, including native USB 3.0 and full 4K Advanced Format support, Microsoft account integration, Windows Store, the ability to boot from USB Flash drives with Windows To Go, and easier system restore options, among others.
  23. 23. CONCLUSION:Windows 8 give strong competition to mobile computing, especially the tablet market OS such as Apple OS and Android. So far it has been quite successful and has got the rival developers moving with new ideas. Windows 8 provides great experience on large screens and is a wonder for palm sized smart phones. The desktop computers are quite powerful and have fetched wonderful speeds and have witnessed quite a number of futuristic apps already. The Start screen is more innovative and the start menu is definitely totally different than that in previous versions which might not be cheered by all Windows enthusiasts. We can hope that other hidden features of zooming and multimedia control get popularized after the launch.
