Windows 8 is a new operating system produced by Microsoft that runs on PCs, laptops, tablets and other devices. It introduces significant changes to the graphical user interface and platform, including a new "Metro" interface design. Windows 8 allows developers to create apps using HTML5/JavaScript, C/C++ and C#/XAML for the new Metro-style app platform. It also provides faster performance, built-in security features, and integration with cloud services and Microsoft accounts.

A multi-touch screen is also required to take advantage of touch
input. For Metro applications, a screen resolution of
1024x768 or higher is required.

5. 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 bold underpinnings of the re-
imagination of the 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 typography-based design
language created by Microsoft, 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.

7. Who To Use & What To Use
• Web developers can use their HTML5, CSS3, and JavaScript
skills to build native applications for Windows.
• NET Developers can use XAML, C#, and Visual Basic to build
beautiful Metro style apps.
• Game developers can use the power of DirectX 11.1 to build
amazing, immersive gaming experiences.
• Driver developers can use the new, integrated Microsoft
Visual Studio development environment to increase
productivity.

8. Features
 Windows Live ID Integration
With Windows 8 you could now move to clouds.
With this new feature you can integrate your local
account with Windows Live ID account and
synchronize your data online. Undoubtedly it’s one of
the remarkable features as it ensures that whether your
system crashes or you lose your device, all your data
will be safe and secure.

9. Picture/pattern password
Secure passwords are hard
to memorize.
You can perform gestures on
a picture of your choice to log
in or otherwise a pattern.
 The only problem I see is
that gestures are easy to spot
by someone at your back.

10. Faster Hybrid Boot
This feature will combine the shutdown and hibernate
process of earlier version of Windows thus booting Windows
in 8 to 10 seconds on supported machines.

11. Internet Explorer 10
Windows 8 is having a new kind of browsing application in its
package called Internet explorer 10.

12. Plug-in Free Browsing
 Not only does IE 10
significantly change the
UI, it also changes the way
you will be browsing. IE
10 is favoring HTML 5
over the traditional plug-in
architecture and will
actually run by default
with no plug-in.

13. Windows 8 is a new kind of device combining laptop, desktop
and tablet operating system together.
You can have 10-inch touch-only tablets, big screen in your
living room or massive gaming systems and business desktops.

Metro style User Interface

14. Simpler Task Manager
Windows 8 will come with
a revolutionary new Task
Manager. The Task Manager
will have two kind of
views, simple and advanced.
In simple view you will be
able to see list of running
applications and an end task
button to simply kill a
running task.

15. All New Windows Explorer
 The first thing you will
notice when you launch
your Windows explorer is
the ribbon interface.
 The new ribbon menu will
bring all your frequently
used file operation
commands right in front of
you and thus next time.

16. You can put two apps on screen side by side or access
traditional Windows desktop for richer apps.

17. Better File Operations
What you’ll also notice is
the new pause feature.
Finally, you can pause a copy
operation in the middle of it
Firstly, when you copy
stuff around, especially when
you perform multiple copy
operations, all of the info is
consolidated into one dialog.
No more doing 10 copies and
having 10 different windows
pop up.

18. If you click More Details, you
can see the speed of the data
transfer the trend and the amount
of data left in the transfer.
 Windows 8 will feature enhanced
real-time information on how long it
will take to copy a file unlike the
crappy clocks of previous versions
of Windows.
Users will be able to see
operational graphs, transfer speeds
as well.

19. Refresh/Reset Your PC
 Two cool new features of Windows 8 are the refresh
and reset options.
 Reset will remove all your personal data, apps, and
settings and reinstall Windows.
 Refresh will keep all data, apps and settings and
reinstall Windows.

20. Built-in Antivirus
Moreover, Windows 8 has an antivirus present
inside the kernel of the operating system.
This means that your system won’t boot if a
corrupt USB device is plugged in.
It sounds impressive though I don’t know whether
it would pass the test of time…. and viruses
I genuinely believe that Microsoft is finally ready
to launch an OS which will take the world by storm!

21.  Along with the new UI interface, there have been many
improvements in Windows 8 for scaling to different
screen resolutions, screen sizes and pixel densities.
 Even though this may seem minor, you will be able to
use Windows 8 on everything from a small Windows
phone to a giant 30 inch screen with a 2560 1600
resolution
Scaling for Different Screen Sizes

22. Windows Store and Apps
 The Metro interface looks and feels like a Smartphone
or tablet OS, and following that theme is the inclusion
of the Windows Store in Windows 8.
 This online shop front is stuffed full of Windows apps -
each designed to run on x86 Windows PCs, laptops and
tablets, as well as ARM tablets and smart phones.
 Windows 8 apps follow the same design principle as
Metro - being constructed of cascading live tiles of
information, in primary colors.

23. Security, Cloud, Task manager
 There are a couple of other relatively minor, but
significant changes in Windows 8 that may make it
worth an upgrade for Windows 7 users.
 Windows 8 has a cloud focus to it which might be a
tempting feature.
 Microsoft stores all your settings and customizations in
the cloud so whenever you log on to a Windows 8
machine you will have it looking and working your
way.

24. Speed
 That's about it in terms of significant feature
changes, but Microsoft would have us believe that
Windows 8 is much faster than Windows 7 - it certainly
works on the same hardware, which removes one
barrier to upgrade.

25. Introduction to Windows App
Development
• Before you start...
• Choose C# and Visual Basic
• Part 1: Create a "Hello, world" app
• Step 1: Create a new project in Visual Studio
• Step 2: Start the app
• Step 3: Modify your start page
• Step 4: Create an event handler
• Part 5: Style the start page

26. Step 1: Create a new project in
Visual Studio
• Launch Visual Studio Express 2012 for Windows 8.
• The Visual Studio Express 2012 for Windows 8 start screen
appears.
• (Going forward, we'll refer to Visual Studio Express 2012
for Windows 8 as just "Visual Studio".)
• Select File>New Project.
• The New Project dialog appears. The left pane of the dialog
lets you select the type of templates to display.
• In the left pane, expand Installed > Templates, then expand
Visual Basic or Visual C# and pick the Windows Store
template type. The dialog's center pane displays a list of
project templates for Windows Store apps.

27. •In the Name text box, enter "HelloWorld".
Click OK to create the project

28. Although the Blank App is a minimal
template, it still contains a lot of files:
A manifest file (package.appxmanifest) that
describes your app (its
name, description, tile, start page, and so on)
and lists the files that your app contains.
A set of large and small logo images (logo.png
and smalllogo.png)to display in the start screen.
XAML and code files for the app (App.xaml
and App.xaml.cs/.vb) .
A start page (MainPage.xaml) and an
accompanying code file (MainPage.xaml.cs/.vb)
that run when your app starts.

29. Step 2: Start the app
• At this point, you created a very simple app.
• The splash screen disappears, and then your
app appears. It contains a black screen and the
title "My Application".

30. • <Application
• x:Class="HelloWorld.App"
• xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
• xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
• xmlns:local="using:HelloWorld"
• RequestedTheme="Light">
•
• <Application.Resources>
• <ResourceDictionary>
• <ResourceDictionary.MergedDictionaries>
• <!--
• Styles that define common aspects of the platform look and feel
• Required by Visual Studio project and item templates
• -->
•
App.xaml

31. • <ResourceDictionarySource="Common/StandardStyles.xaml"/>
• </ResourceDictionary.MergedDictionaries>
• <Stylex:Key="BigGreenTextStyle" TargetType="TextBlock">
• <SetterProperty="Foreground" Value="Green"/>
• <SetterProperty="FontSize" Value="36"/>
• <SetterProperty="FontFamily"

• <SetterProperty="TextTrimming" Value="WordEllipsis"/>
• <SetterProperty="TextWrapping" Value="Wrap"/>
• <SetterProperty="Typography.StylisticSet20" Value="True"/>

• <SetterProperty="Typography.CaseSensitiveForms" Value="True"/>
• </Style>
•
• </ResourceDictionary>
• </Application.Resources>
• </Application>

33. Conclusion
 These ten features only touch the surface of what is
available to developers for building applications that
target the new Windows 8 Metro platform. Microsoft
has created a platform that allows you to develop
using the language and design tool of your
choice, implements complex interfaces in a simple
way, and creates unprecedented interoperability
between different applications
