FEATURES OF

WINDOWS 7

CLASS:- IX A

ROLL NO.- 22

Some of the new features included in Windows 7 are advancements in

touch, speech, and handwriting recognition, support for virtual hard

disks, support for additional file formats, improved performance

on multi-core processors, improved boot performance, and kernel improvements.

Shell and user interface

Windows 7 retains the Windows Aero graphical user

interface and visual style introduced in the operating system's

predecessor, Windows Vista, but many areas have seen enhancements.

Unlike Windows Vista, window borders and the taskbar do not turn opaque when a window is maximized when

Windows Aero is active; instead, they remain translucent.

DEVICESThere are two major new user interface components for device management in Windows 7, "Devices and

Printers" and "Device Stage". Both of these are integrated with Windows Explorer, and together

provide a simplified view of what devices are connected to the computer, and what capabilities

they support.

Mobility enhancements Multi-touch support

Hilton Locke, who worked on the Tablet PC team at Microsoft, reported on December 11, 2007 that Windows 7 will have new touch features on devices supporting multi-touch. An

overview and demonstration of the multi-touch capabilities, including a virtual piano program, a mapping and directions

program and a touch-aware version of Microsoft Paint.

Sensors Windows 7 introduces native support for sensors, including accelerometer sensors, ambient light sensors, and location-based sensors; the operating system also provides a unified

driver model for sensor devices.

Power managementBattery notification messages

Unlike previous versions of Windows, Windows 7 is able to report when a laptop battery is in need of a

replacement. The operating system works with design capabilities present in modern laptop batteries to

report this information.Power analysis and reporting

Windows 7 introduces a new /Energy parameter for the powercfg command, which generates

an HTML report of a computer's energy efficiency and displays information related to devices or settings.

GRAPHICSSupport for color depths of 30 and 48 bits is

included, along with the wide color gamut scRGB. The video modes supported in Windows 7 are 16-bit sRGB, 24-bit sRGB, 30-bit sRGB, 30-bit with extended

color gamut sRGB, and 48-bit scRGB.Each user of Windows 7 and Server 2008 R2 has individual DPI settings, rather than the machine having a single setting as in previous versions of

Windows. DPI settings can be changed by logging on and off, without needing to restart.

File systemOver time, several technologies have been

incorporated into subsequent versions of Windows to improve the performance of the operating system on

traditional hard disk drives (HDD) with rotating platters. Since Solid state drives (SSD) differ

from mechanical HDDs in some key areas, it is beneficial to disable certain optimizations and add

others, specifically for SSDs. Windows 7 incorporates many engineering changes to reduce the frequency

of writes and flushes, which benefit SSDs in particular since each write operation wears the flash memory.

Boot performanceAccording to data gathered from the Microsoft Customer Experience Improvement Program (CEIP), 35% of Vista SP1 installations boot up in 30 seconds or less. The more lengthy boot times on the remainder of the machines are mainly due to some services or programs that are loaded but are not required when the system is first started. Microsoft's Mike Fortin, a distinguished engineer on the Windows team, noted in August 2008 that Microsoft has set aside a team to work solely on the issue, and that team aims to "significantly increase the number of systems that experience very good boot times". They "focused very hard on increasing parallelism of driver initialization". Also, Microsoft aims to "dramatically reduce" the number of system services, along with their demands on processors, storage, and memory.

MULTIMEDIAWindows Media Center in Windows 7 has retained much of the

design and feel of its predecessor, but with a variety of user interface shortcuts and browsing capabilities. Playback of H.264 video both locally and through a Media Center Extender is supported. Some

notable enhancements in Windows 7 Media Center include a new mini guide, a new scrub bar, the option to color code the guide by

show type, and internet content that is more tightly integrated with regular TV via the guide. All Windows 7 versions now support up to four tuners of each type (QAM, ATSC, CableCARD, NTSC, etc.). When

browsing the media library, items that don't have album art are shown in a range of foreground and background color combinations

instead of using white text on a blue background.

SECURITYA new user interface for User Account Control has

been introduced, which provides the ability to select four different levels of notifications, one of these notification settings, Default, is new to Windows 7. Geo-tracking capabilities are also available in

Windows 7. The feature will be disabled by default. When enabled the user will only have limited control

as to which applications can track their location.The Encrypting File System supports Elliptic-curve

cryptographic algorithms (ECC) in Windows 7.

NETWORKING1. DirectAccess, a VPN tunnel technology based

on IPv6 and IPsec. DirectAccess requires domain-joined machines, Windows Server 2008 R2 on the DirectAccess

server, at least Windows Server 2008 domain controllers and a PKI to issue authentication certificates.

2. BranchCache, a WAN optimization technology.3. The Bluetooth stack includes improvements introduced

in the Windows Vista Feature Pack for Wireless, namely, Bluetooth 2.1+EDR support and remote wake from S3 or

S4 support for self-powered Bluetooth modules.

Management featuresWindows 7 contains Windows PowerShell 2.0 out-of-the-

box, which is also available as a download to install on older platforms:

1. Windows Troubleshooting Platform2. Windows PowerShell Integrated Scripting Environment.

3. PowerShell RemotingOther new management features include:

1. AppLocker2. Group Policy Preferences

3. The Windows Automation API

Upgraded componentsWindows 7 includes Internet Explorer 8.NET

Framework 3.5 SP1, Internet Information Services (IIS) 7.5, Windows Installer 5.0 and a

standalone XPS Viewer. Paint, Calculator, Resource Monitor and WordPad have also been updated.

OTHER FEATURES1. Windows 7 improves the Tablet PC Input Panel to make faster

corrections using new gestures, supports text prediction in the soft keyboard and introduces a new Math Input Panel for

inputting math into programs that support MathML.2. Windows 7 introduces a new Problem Steps Recorder tool that

enables users to record their interaction with software for analysis and support.

3. As opposed to the blank start-up screen in Windows Vista, Windows 7's start-up screen consists of an animation featuring

four colored light balls.4. The Starter Edition of Windows 7 can run an unlimited number of

applications, compared to only 3 in Windows Vista Starter.5. For developers, Windows 7 includes a new networking API with

support for building SOAP-based web services in native code.
