Windows 7 includes a number of new features, such as advances in touch
and handwriting recognition, support for virtual hard disks, improved
performance on multi-core processors,[13][14][15][16] improved boot
performance, DirectAccess, and kernel improvements. Windows 7 adds
support for systems using multiple heterogeneous graphics cards from
different vendors (Heterogeneous Multi-adapter), a new version of Windows
Media Center,[17] 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 for length,
weight, temperature, and several others. 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.[18] 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. ReadyBoost on 32-bit editions now supports
up to 256 gigabytes of extra allocation. 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.[19] 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.[20] Windows 7 also
supports images in RAW image format through the addition of Windows
Imaging Component-enabled image decoders, which enables raw image
thumbnails, previewing and metadata display in Windows Explorer, plus
full-size viewing and slideshows in Windows Photo Viewer and Windows
Media Center.[21]

The taskbar has seen the biggest visual changes, where the Quick Launch
toolbar has been replaced with the ability to pin 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.[22] 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.[23] In touch-enabled displays such as touch screens,
tablet PCs, etc., this button is slightly wider to accommodate being
pressed with a finger.[24] 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.[25] 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, such that the windows
vertically take up half the screen. 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.

For developers, Windows 7 includes a new networking API with support for
building SOAP-based web services in native code (as opposed to .NET-based
WCF web services),[26] new features to shorten application install times,
reduced UAC prompts, simplified development of installation packages,[27]
and improved globalization support through a new Extended Linguistic
Services API.[28] At WinHEC 2008 Microsoft announced that color depths of
30-bit and 48-bit would be supported in Windows 7 along with the wide
color gamut scRGB (which for HDMI 1.3 can be converted and output as
xvYCC). 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.[29][30] Microsoft has also implemented better support for solid-
state drives,[31] including the new TRIM command, and Windows 7 is able
to identify a solid-state drive uniquely. Microsoft is planning to
support USB 3.0 in a subsequent patch, support not being included in the
initial release due to delays in the finalization of the standard.[32]
The Windows 7 taskbar

Internet Spades, Internet Backgammon and Internet Checkers, which were
removed from Windows Vista, were restored in Windows 7. Windows 7
includes Internet Explorer 8 and Windows Media Player 12. Users are also
able to disable many more Windows components than was possible in Windows
Vista. New additions to this list of components include Internet
Explorer, Windows Media Player, Windows Media Center, Windows Search, and
the Windows Gadget Platform.[33] Windows 7 includes 13 additional sound
schemes, titled Afternoon, Calligraphy, Characters, Cityscape, Delta,
Festival, Garden, Heritage, Landscape, Quirky, Raga, Savanna, and
Sonata.[34] A new version of Microsoft Virtual PC, newly renamed as
Windows Virtual PC was made available for Windows 7 Professional,
Enterprise, and Ultimate editions.[35] It allows multiple Windows
environments, including Windows XP Mode, to run on the same machine.
Windows XP Mode runs Windows XP in a virtual machine and redirects
displayed applications running in Windows XP to the Windows 7
desktop.[36] Furthermore, Windows 7 supports the mounting of a virtual
hard disk (VHD) as a normal data storage, and the bootloader delivered
with Windows 7 can boot the Windows system from a VHD; however, this
ability is only available in the Enterprise and Ultimate editions.[37]
The Remote Desktop Protocol (RDP) of Windows 7 is also enhanced to
support real-time multimedia application including video playback and 3D
games, thus allowing use of DirectX 10 in remote desktop
environments.[38] The three application limit, previously present in the
Windows Vista Starter Edition, has been removed from Windows 7.[39]
Removed features
Main article: List of features removed in Windows 7
Certain capabilities and programs that were a part of Windows Vista are
no longer present or have been changed, resulting in the removal of
certain functionalities. These 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[40] and Windows Mail – are not included
with Windows 7, but applications with close functionality are instead
available for free in a separate package called Windows Live Essentials
which can be downloaded on the Microsoft website. Although Windows
Ultimate Extras was removed, many of the extras can be installed
separately.[41] Most popular extras were Microsoft Texas Hold 'em,
Microsoft Tinker, and Windows DreamScene.[42] InkBall may also be
installed into Windows 7.
