What is new in Windows 7? 1. Introduction Windows 7 is technically an evolution of Windows Vista and considered the best version of Windows because its faster, more powerful, non-intrusive, stable, secured, and retains just enough animation and attractiveness of Windows Vista . However, these are just broad descriptions of Windows 7 and do not exactly tell what is actually new about it. For this reason, this study explores the evolution of Windows in order to detail the differences and changes in their characteristics through the years. This in particular include the transition from DOS-based Windows to Windows XP architecture emphasis on reliability and performance, Windows Vista’s appealing design and expansion of XP’s functionality, the similarity between Windows Vista and Windows 7, and features that made Windows 7 unique. 2. Evolution of Microsoft Windows The history of Microsoft Windows can be traced back to MS-DOS, an operating system originally created for IBM personal computers introduced in 1981. MS-DOS, compared to UNIX at that time is a very limited as it does not support multitasking and various features of x86 processor. For this reason, Microsoft over the years improved MS-DOS and introduced Windows, a GUI or Graphical User Interface for MS-DOS . The first three Windows version such Windows 1.x, Windows 286 (2.x) and Windows 386 were nothing but graphic-based operating environment with active application displayed in movable resizable window and ran on top of MS-DOS platform. Windows 1.0 was Microsoft first attempt at a GUI and released in 1983. This version of Windows is not an operating system but an extension of DOS using bitmap displays, support VGA or Video Graphics Array, 16 colours at 640x480 resolution, mouse for easy navigation, switch between programs, and eliminate the need to type commands at the DOS command prompt. Released in 1987, Windows 2.0 allowed users to control screen layout, overlap windows, icons to represent programs, and support the 286 processor. Windows 3.0 was released in 1990 with improved graphics, new icons, can use memory beyond 640K, comes with SDK or Windows Software Development Kit for writing Windows-based applications, and VxDs or virtual device drivers to minimise hardware dependencies . A new version of Windows (Windows 3.1 and Windows for Workgroups 3.1) that is faster compared to previous versions, support multimedia and 16 bit applications, true type fonts, drag and drop, and so on, and the last version to work on top of DOS platform was introduced in 1992 . Windows 3.1 added multimedia functionality such as connecting external musical instruments and MIDI devices. It also support True Type font, terminate hung application, OLE or Object Linking and Embedding support, and the ability to close applications by pressing key combinations Ctrl+Alt+Del. Windows for Workgroup on the other hand was the first Microsoft OS to support peer-to-peer network, file and printer sharing, email client, and workgroup scheduler. Windows 3.11 was released a year later in 1993 but no new feature was added. This version is only correcting problems with previous version, which were mostly network problems . In same year, Microsoft launched Microsoft Windows NT 3.1, a full 32-buit operating system with GUI similar to Windows 3.1 but it was only sold to businesses . In August 1995, Microsoft released Windows 95, a new consumer-oriented version of Windows with redesigned GUI, independent of DOS, multitasking, support up to 4GB of linear address memory, can run 32-bit applications and able exploit almost all features of the Intel 80386 processor . It also introduced Plug-and-Play to make hardware installation easier, dial-up networking for internet and other network connection, support long filenames, pre-emptive multitasking. Windows 95b or OSR2 was an improved version of Windows 95 with USB support and FAT32 file system but was only made available to OEM or Original Equipment Manufacturers . In 1996, Windows NT 4.0 was released with GUI similar to Windows 95 that was followed by another version in 2000 called Windows NT 5.0. Windows 95 evolved and after 3 years, Microsoft released Windows 98 and Windows ME. Windows ME is the last of Windows 3.x based operating system . Windows 98 was released on June 25, 1998 as a retail upgrade to Windows 95 supporting DVD reading and use of USB devices. Windows 98 made applications open and close faster and it include FAT32 converter for overcoming the 2GB limitations imposed by DOS. It also support SCSI devices and added features such as Disk Cleanup, Internet Explorer 4.0, and Active Desktop. The second edition of Windows 98 or Windows SE was also released in the same year as an incremental update. This version includes enhanced multimedia, home networking, and Internet browsing. It also introduced Internet Connection Sharing where a particular computer running Windows 98 SE can function as NAT or Network Address Translation server for other computers in the home network. Moreover, it include other useful networking features such as NetMeeting conferencing program and enhanced Internet Explorer 5 . Finally, Microsoft released Windows ME or Windows Millennium Edition in September 14, 2000.This version of Windows is the operating system built around the MS-DOS kernel. It include support for digital media through built-in programs such as Image Acquisition (downloading images from digital cameras), Movie Maker (recording and editing digital video medial files), and Windows Media Player to play music and video files. Other new features include System Restore for restoring deleted files, System File Protection to prevent applications from changing important OS files, and Home Networking Wizard to make adding network computers and peripherals easier . Windows 2000 or Windows NT 5.0 was released in year 2000 but in 2001 Microsoft decided to discontinue its MS-DOS-based versions of Windows and introduced Windows XP or Windows NT 5.1. Windows XP has two main editions, the Home and Professional Edition . The Home Edition as the name implies is the first home-oriented version of Windows that does not contain any traces of MS-DOS. Window XP Home Edition combines improved version multimedia and crash recovery features of Windows 98 and Windows ME. It has the reliability of Windows 2000 particularly in accommodating combination of old and new hardware and software . Windows Home and Windows Professional is almost identical in terms of GUI and other features but the latter comes with Internet Information Services or IIS that let user host web sites and FTP sites. It is allow XP machines to run Simple Mail Transfer Protocol or SMTP service for sending email . Windows XP Professional supports up to two processors and ability to join a domain unlike Windows Home Edition . Windows XP is designed for multiple users and has five different versions. The main versions as mentioned earlier are Home and Professional Edition. The editions include Table PC Edition, Media Centre Edition, and 64-bit Edition. All versions of Windows XP support FAT, FAT32, and NTFS. It has an intelligent GUI, provides ability to customise the desktop environment, and comes with additional utilities such as Remote Assistance, Remote Desktop, Windows Media Player 8, Windows Messenger, and Windows Movie Maker. It is also work with a variety of hardware components or those include in HCL or Hardware Compatibility List . Windows XP remains the dominant Windows operating system for many years until Windows Vista was introduced in 2007 followed by Windows 7 in 2008. 3. Windows XP As mentioned earlier Windows XP is the first attempt of Microsoft to eliminate Windows dependence in MS-DOS. Therefore, unlike other versions of Windows including Windows 95 and 98, Windows XP does not include DOS . In fact, Windows XP is in itself an operating system with primary components – environment subsystem and executive services as shown below. Figure 1- Components of Windows XP architecture The environment subsystems according to provide runtime support for application under the control of one operating system. Unlike common belief that operating systems exist to run programs or applications, Windows XP operating system works through processes and threads. For instance, a process in Windows XP defines the operating environment in which a particular application or major operating component runs. Each process has its own private memory space, security descriptors, execution priority level, processor-affinity data, and a number of threads for the process. Similarly, a thread is recognised as the basic executable unit that contains information placeholder associated with a program capable of handling multiple simultaneous activities. For instance, an application such as Microsoft World performing spelling and grammar checks while user writes. The unique features of Windows XP in terms of reliability and performance are summarised below: Table 1 - New Features of Windows XP ( New Features Availability Provides access to all documents and settings regardless of computer user use to log on. Professional Edition only Allows access to files and folders on network share Professional Edition only Support running of multiple application simultaneously Home and Professional Automatic System Recovery or ASR Professional Edition only Support automatic 802.1x wireless network configuration Home and Professional Automatic installation, configuration, repair or removal of software applications CD-Burning and file dragging through Windows Explorer Home and Professional File encryption through EFS or Encrypting File System Fast booting and resume times Home and Professional File-level access control through administrative privileges Access to Microsoft Knowledge Base through Help and Support Centre Home and Professional Home Networking Home and Professional Internet Connection Firewall Home and Professional Internet Information Service/ Personal Web Server Professional Edition only Multilingual User Interface Professional Edition only Multiprocessor support (up to two microprocessors) Professional Edition only My Pictures and My Music folders for organising pictures and music Home and Professional Network Setup Wizard Home and Professional New and more appealing user interface Home and Professional Taskbar button Home and Professional Computer management and security tools Professional Edition only Remote Desktop and Remote Installation Service Professional Edition only Scanner and Camera Wizard Home and Professional Search Companion Home and Professional Start Menu and System Restore Home and Professional Recycle Bin Home and Professional Welcome Screen and Task Panes Home and Professional Windows Media Player and Windows Messenger Home and Professional Service Packs for Enhancement and Security Home and Professional Moreover, it is important to note that unlike previous versions of Windows, Windows XP include free update or service packs that contains fixes and enhancements such as advanced security features to protect computers from harmful viruses, works, and hackers . 4. Comparison between Windows XP, Windows Vista and Windows 7 Released in 2007, Windows Vista is designed to expand Windows XP’s functionality, increased security, reliability, further enhance digital media, introduce impressive Aero 3D interface. Similar to other Windows version, Windows Vista comes in various editions such Home, Business, and Enterprise Editions . Windows 7 according to on the other hand combines the best of Windows XP and Windows Vista. It has six different versions such as Windows Starter, Home Basic, Home Premium, Professional, Enterprise, and Ultimate. Compared to XP the following table shows the unique features of Windows Vista. Figure 2- Windows Vista features compared to XP Windows Vista New Features Availability in XP .NET Framework 3.-0 None Support for 64-bit processor None Ad-hoc backup and recovery of user files and folders None Anti-phishing tools None Automatic hard disk defragmentation Basic Complete Backup and Restore facility Basic Better control of device drivers installation Basic Desktop deployment tools for managing networks None Ease of Access Centre None Encrypting File System Basic File Tagging and file-based image format None Games explorer None I/O Prioritization Basic Improved file and folder sharing Basic Improved peer networking Basic Improved power management Basic Improved VPN support Basic Improved Wireless Networking Basic Instant Search None Internet Explorer 7 Older version IPv6 and IPv4 support None Support 32 bit and 64 bit system 16 and 32 bit only Multiple user interface language Basic Native DVD playback None Network Access Protection Basic Network and Sharing Centre Basic Network Diagnostic and Troubleshooting None New Games Basic Improved TCP/IP stack Basic Support for offline folders None Parental Controls None Performance and Hardware Tools None Pluggable logon authentication architecture None Policy-based QOS for networking None Scheduled, networked, incremental, and automatic backup.

Windows Vista did not take off the way Microsoft expected as it requires high-end machines to run properly. For instance, Windows Vista typically needs a dual core processor, high-end graphics card, and at least 2GB of system memory . Similarly, Windows 7 is significantly different from Windows XP and earlier Windows’ versions. Windows 7 is somewhat similar to Vista in terms of interface and architecture . As indicated in the table below, Windows 7 has almost similar features with Windows Vista.
