Hardware recommendations

Windows 8 provides a terrific experience on the same hardware that runs Windows 7. Table 1-1 describes the

hardware recommendations for Windows 8. In fact, you might even notice that PCs seem to work even better

after upgrading from Windows 7 to Windows 8.

Table 1-1 Windows 8 Hardware Recommendations

COMPONENT RECOMMENDATION

Processor 1 GHz or faster

Memory 32-bit PCs: 1 GB

64-bit PCs: 2 GB

Hard disk space 32-bit PCs: 16 GB

64-bit PCs: 20 GB

Graphics card Microsoft DirectX 9 graphics device with WDDM driver

Additionally, some Windows 8 features require other hardware components:



To use touch, you need a tablet or a monitor that supports multi-touch.



To access the Windows Store to download and run apps, you need an active Internet connection

and a screen resolution of at least 1024 x 768.



To snap apps, you need a screen resolution of at least 1366 x 768.

Hardware innovation

Hardware innovation is broad in Windows 8, and there are a few key areas where Microsoft has worked

extensively with its partners. The following sections describe some of the things you and your users will

notice quickly about PCs built for Windows 8—either at work or at a retail store.

Touch

Touch is clearly front-and-center for Microsoft. For example, the company is requiring that touch displays

support a minimum of five-fingers, and it is working with its partners to deliver touch-optimized devices. To

ensure a great user experience with touch, Microsoft has done extensive research into:



The response times required for touch.



The sensitivity and precision required of a digitizer.



The user experience of a flush bezel.

These requirements are enforced with the Windows 8 Hardware Certification Requirements. You can learn

more about these requirements on the "Windows Hardware Certification" page at

http://msdn.microsoft.com/en-us/library/windows/hardware/gg463010.aspx.

Long battery life

One of the key design tenets of Windows 8 is to enable long battery life. With Windows 8, a new class of

ultrathin PCs and tablets can turn on instantly, can run all day on a single charge, and stay connected to the

Internet—so users’ PCs are ready when they’re ready.

Thinner, lighter, faster

As you have seen with today’s ultrabooks, PCs are already thinner and lighter than ever. This will only

continue with Windows 8. There will be thin and light tablets and ultra-portables that start and run faster

than today’s PCs. Even installing Windows 8 on an existing PC will improve its performance because of the

improvements we’ve made in the core operating system.

Sensors and security

With Windows 8, Microsoft will enable developers to take advantage of hardware innovation such as:



Low-power Bluetooth



GPS



Gyroscopes



Accelerometer

You'll also be able to take advantage of security hardware technologies like Trusted Platform Module

(TPM) and Unified Extensible Firmware Interface (UEFI) boot.

New form factors

Microsoft believes that users should have a choice. To that end, PCs will come in a variety of form factors,

from tablets to convertibles to ultra-portables to all-in-one PCs. One day, you might even see designs that

you would not have thought possible. Together with its OEM partners, Microsoft will provide great devices

for every work style:



Devices for executives that are innovative, portable, powerful.



Devices optimized for enterprise knowledge workers and everyday business tasks.



Devices that are specialized and unique for specific tasks.



Industrial devices like ruggedized machines in oil rigs and manufacturing lines.



Varieties of companion devices that present new and fun possibilities.

Devices for Windows 8 are about choices, because Microsoft believes the device has to fit the job.

Microsoft and its ecosystem are committed to providing choices to our customers.

Windows 8 editions

Chapter 5, "Preparing for deployment," contains a table that describes the specific features you will find in

each edition of Windows 8. For now, the following list summarizes them:



Windows 8

Windows 8 is the basic stock-keeping unit (SKU) for home users. It includes the core

feature set that home users require but does not include key business features, such as support for

the ability to join domains, process Group Policy, and so on.



Windows 8 Pro

Windows 8 Pro is for small- and medium-sized businesses. It delivers new levels

of productivity, security, and mobility—without sacrificing performance or choice. It provides

enhanced features that help to easily connect to company networks, access files on the go, encrypt

data, and more.



Windows 8 Enterprise

Windows 8 Enterprise edition is available through Windows Software

Assurance. It includes all the capabilities of Windows 8 Pro, plus premium features designed to meet

the mobility, productivity, security and manageability, and virtualization needs of today’s large

businesses. Key examples are Windows To Go, DirectAccess, BranchCache, AppLocker, VDI, and

Windows 8 app deployment. You will learn about these features in this book.



Windows RT Devices

Windows RT Devices run low-powered ARM processors, which helps OEMs

build devices with long battery lives and new form factors (thin, light, and sleek devices). Also,

Windows RT Devices are built on a new paradigm (preconfigured system on certified hardware),

which helps ensure that users have high-quality and predictable experiences over time. While

Windows RT Devices offer the great benefits this chapter just mentioned, they have commonality

and shared code with Windows 8, offering a consistent, great Windows experience. For example,

Windows RT Devices support the new UI (including desktop). Both Windows RT Devices and

Windows 8 can run apps from the Windows Store. Windows RT Devices are compatible with most

peripherals, since they include class drivers for most peripherals, and the majority of mice,

keyboards, printers, and USB storages are supported out of the box.

Getting started with Windows 8

Microsoft makes getting started with your Windows 8 evaluation easy. MSDN and TechNet subscribers can

download Windows 8 from the subscriber downloads area. You can also download a Windows 8 Enterprise

evaluation from the Downloads page on TechNet at http://www.microsoft.com/technet/downloads.

You can evaluate Windows 8 in a VM. By doing so, you will experience the vast majority of features that

this book describes. If you want to experience touch, however, then you must install Windows 8 on a PC with

a touch-enabled display or a tablet PC.

CHAPTER 2

Experiencing Windows 8

Consumers often say that they have to choose between the full productivity experience of a PC and the

convenience of a tablet. Tablets historically presented productivity challenges, because most business

desktop apps don't run on non-Windows tablets. Tablets also challenged IT because it can be difficult to

manage and secure non-Windows tablets.

However, with an x86 Windows 8 tablet, users can have a no-compromise tablet experience, so choosing

between productivity and convenience is no longer necessary. Microsoft Windows 8 gives users productivity,

convenience, and mobility. They can use the familiar Windows user interface, their desktop line-of-business

(LOB) and productivity apps, and peripherals that they use today on Windows 7.

Windows 8 delivers a touch-first experience, along with full support for mouse and keyboard, enabling

users to move between work and personal activities easily and effortlessly. The Windows 8 user interface

provides quick access to critical data, and Windows 8 apps are always on and always connected to help keep

them up-to-date.

IT pros don't need to compromise either. Windows 8 provides the manageability and security that you

need. Also, you can take advantage of your existing management and security infrastructure for managing

Windows 8 tablets.

In both cases, features that were great in Windows 7 are even better in Windows 8. With Windows 8, users

have the best of both worlds: a powerful new way of working with their PCs and the flexibility and power of

the Windows desktop. And Windows 8 extends the deployment, management, and virtualization capabilities

of Windows 7 with new capabilities.

Like Windows 7—Only better

Windows 8 uses the same management tools that you already use to support Windows 7 in your

organization. Tools like System Center 2012 Configuration Manager, Microsoft Deployment Toolkit (MDT)

2012, and the Microsoft Diagnostics and Recovery Toolset (DaRT) have been updated for Windows 8—not

just updated, but really enhanced.

Additionally, Windows 8 contains all of the security and reliability features that you've come to expect

from Windows. As you'll learn in this book, the changes in Windows 8 are incremental from Windows 7. For

an IT pro, these changes enhance supportability and security. For example, there are new refresh and

recovery options available with Windows 8. This means that you'll spend less time supporting Windows 8.

The Windows 7 desktop features you love, like Jump Lists, the Taskbar, and Snapping, are still there in

Windows 8. You can pin items to the taskbar in Windows 8 and you can use thumbnails in Windows 8 too.

The desktop experience is just like Windows 7.
