A Technical Seminar On

Introduction Windows 8 is an operating system produced by

Microsoft for use on personal computers, including home and business desktops, laptops, tablets, and home theater PCs.

Windows 8 introduces significant changes to the operating system's graphical user interface and platform.

such as a new interface design incorporating a new design language used by other Microsoft products.

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.

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.

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 VisualStudio development environment to increase productivity.

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.

Picture/pattern passwordSecure 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.

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.

Internet Explorer 10

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

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.

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

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.

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.

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

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.

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.

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.

Built-in AntivirusMoreover, 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!

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

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.

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.

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.

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.
