Windows 7 SP1 Ultimate 64 Bitand 32 bit fully activated

                 This a version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs, and media center PCs. Windows 7 was released to manufacturing on July 22, 2009, and reached general retail availability on October 22, 2009, less than three years after the release of its predecessor, Windows Vista. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time. Windows 7 will be succeeded by Windows 8, which has no release date as of yet.

                 Unlike its predecessor, Windows Vista, which introduced a large number of new features, Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware with which Windows Vista is already compatible. Presentations given by Microsoft in 2008 focused on multitouch support, a redesigned Windows Shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and performance improvements. Some standard applications that have been included with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, and Windows Photo Gallery, are not included in Windows 7; most are instead offered separately at no charge as part of the Windows Live Essentials suite.

New And Changed Features

• Windows 7 includes a number of new features, such as advances in touch and handwriting recognition, support for virtual hard disks, improved performance on multicore processors, improved boot performance, DirectAccess, and kernel improvements.
• Windows 7 adds support for systems using multiple heterogeneous graphics cards from different vendors (Heterogeneous Multiadapter), a new version of Windows Media Center, a Gadget for Windows Media Center, improved media features, the XPS Essentials Pack and Windows PowerShell being included, and a redesigned Calculator with multiline capabilities including Programmer and Statistics modes along with unit conversion. 
• Many new items have been added to the Control Panel, including ClearType Text 
• Tuner, Display Color Calibration Wizard, Gadgets, Recovery, Troubleshooting, Workspaces Center, Location and Other Sensors, Credential Manager, Biometric Devices, System Icons, and Display. Windows Security Center has been renamed to Windows Action Center (Windows Health Center and Windows Solution Center in earlier builds), which encompasses both security and maintenance of the computer.
• The default setting for User Account Control in Windows 7 has been criticized for allowing untrusted software to be launched with elevated privileges without a prompt by exploiting a trusted application. 
• Microsoft's Windows kernel engineer Mark Russinovich acknowledged the problem, but noted that malware can also compromise a system when users agree to a prompt. Windows 7 also supports images in the RAW image format through the addition of Windows Imaging Componentenabled image decoders, which enables raw image thumbnails, previewing and metadata display in Windows Explorer, plus fullsize viewing and slideshows in Windows Photo Viewer and Window Media Center.
• The taskbar has seen the biggest visual changes, where the Quick Launch toolbar has been replaced with pinning applications to the taskbar. 
• Buttons for pinned applications are integrated with the task buttons. These buttons also enable the Jump Lists feature to allow easy access to common tasks. 
• The revamped taskbar also allows the reordering of taskbar buttons. To the far right of the system clock is a small rectangular button that serves as the Show desktop icon. 
• This button is part of the new feature in Windows 7 called Aero Peek. Hovering over this button makes all visible windows transparent for a quick look at the desktop. In touchenabled displays such as touch screens, tablet PCs, etc., this button is slightly wider to accommodate being pressed with a finger. 
• Clicking this button minimizes all windows, and clicking it a second time restores them. Additionally, there is a feature named Aero Snap, that automatically maximizes a window when it is dragged to the top of the screen. 
• Dragging windows to the left/right edges of the screen allows users to snap documents or files on either side of the screen for comparison between windows. 
• When a user moves windows that were maximized using Aero Snap, the system restores their previous state automatically. 
• This functionality is also accomplished with keyboard shortcuts. Unlike in Windows Vista, window borders and the taskbar do not turn opaque when a window is maximized with Windows Aero applied. Instead, they remain translucent.

Removed Features

• A number of capabilities and certain programs that were a part of Windows Vista are no longer present or have been changed, resulting in the removal of certain functionalities.
• This include the classic Start Menu user interface, some taskbar features, Windows Explorer features, Windows Media Player features, Windows Ultimate Extras and InkBall. 
• Four applications bundled with Windows Vista — Windows Photo Gallery, Windows Movie Maker, Windows Calendar and Windows Mail — are not included with Windows 7, but applications with mostly similar functionality are instead available for free in a separate package called Windows Live Essentials which can be found on the Microsoft website. 
• Although Windows Ultimate Extras was removed, many of the extras are able to be installed. Most popular extras were Microsoft Texas Hold 'em, Microsoft Tinker, and Windows DreamScene. InkBall may also be installed  into Windows 7.
