Features new to Windows 7

Windows 7 brought many updates that made using computers easier and more fun. One big change was better support for touch screens. This let people use their fingers to click and swipe instead of a mouse, making it easier to work on tablets and other touch devices.

The system also got smarter at understanding spoken words, thanks to improved speech recognition. This meant users could talk to their computers and have them listen and respond. Handwriting recognition also got better, so people could write directly on their screens with a stylus or finger, and the computer would understand it.

Windows 7 also made it simpler to use virtual hard disks, which act like extra storage spaces that aren’t physical drives. It supported more file formats, so more types of documents could be opened easily. The operating system worked faster, especially on computers with multi-core processors, and it started up more quickly. These improvements helped make Windows 7 a smoother and more powerful experience for everyone.

Shell and user interface

Windows 7 looks like its predecessor, Windows Vista, but adds many improvements. The window borders and taskbar stay clear when a window is made larger.

Desktop

Windows 7 adds more options to change colors, icons, and sounds. It also includes a new feature that changes the desktop background at set times.

Windows Explorer

Windows Explorer now groups files into libraries, such as Documents, Music, Pictures, and Videos. This makes it easier to find files, even if they are stored in different places. Searching also looks through networked computers if they are set up to share files.

Start menu

The Start menu now shows more links, such as Devices and Printers, Downloads, and HomeGroup. It also includes a search box that can find items on the computer and online.

Taskbar

The taskbar has been redesigned to be taller and clearer, especially on touch screens. Applications can be pinned to the taskbar for quick access. The taskbar also shows previews of open windows and allows quick access to common tasks.

Window management mouse gestures

Windows 7 adds new ways to move and resize windows using the mouse. Windows can be snapped to the sides of the screen to fit neatly next to each other.

Keyboard shortcuts

Windows 7 introduces new keyboard shortcuts to help manage windows and perform common tasks more quickly.

Mobility enhancements

Windows 7 made it easier to use your computer with touch. Some devices could recognize many touches at the same time. These could work with special programs, like a virtual piano, maps, and a touch-friendly version of Microsoft Paint.

The system could also use sensors. These sensors could detect things like movement, light, or where you are. They could help change the screen brightness based on the lighting or show your location in some tools. For safety, these sensors were turned off by default and needed permission to share location details.

Power management

Windows 7 has new ways to help laptops save power. It can tell you when the battery needs fixing by using the battery’s own design.

You can also change how much space is used when the computer goes to sleep. Windows 7 can make this space smaller to fit better. There is a new tool to show how well the computer uses energy. It can also turn off parts of USB ports to save power when they are not used.

Graphics

Windows 7 added new graphics features. It included Direct3D 11, which makes 3D images look better. New tools like Direct2D and DirectWrite help images and text look nicer and faster.

The way Windows shows windows on the screen, called the Desktop Window Manager, was also improved. It works better with different graphics cards and uses less memory. This helps the computer run more smoothly. Users can also change their screen size without restarting the computer.

File system

Windows 7 made changes to work better with different types of storage.

One big change was for solid-state drives (SSDs). SSDs work differently from regular hard drives because they have no moving parts. Windows 7 was updated to help SSDs last longer. It also uses a command called TRIM (if the SSD supports it) to keep these drives working well.

The Enterprise and Ultimate versions of Windows 7 let users use virtual hard disks (VHD) like real drives. This meant you could install and run Windows from a VHD file, offering a new way to have multiple versions of Windows on one computer. However, some features like hibernation would not work when using a VHD.

Windows 7 also improved how it handles removable media like USB drives and camera cards. It became easier to safely remove just one card from a card reader without needing to restart the computer. Additionally, a feature called BitLocker was added to help protect the data on USB drives by encrypting it.

Boot performance

Windows 7 was made to start up faster than older versions. Some computers with Windows Vista took over 30 seconds to start because they loaded extra programs too early. The team for Windows 7 worked to make starting up quicker by improving how the computer gets ready. They also tried to use the computer’s power, space, and memory better to help it start faster.

Kernel and scheduling improvements

Windows 7 improved how it manages tasks and memory to work better with many processors. It changed how it handles tasks in user-mode, which helps programs with many threads run faster. This gives programs more control over their tasks.

The memory system was also improved to use memory better, especially when many programs are reading files at once. Windows 7 can now support up to 256 logical processors, which reduces delays and improves performance. It also introduced "timer coalescing," which helps modern processors save power by grouping tasks together.

Multimedia

Windows Media Center

Windows Media Center in Windows 7 looks mostly the same but has some new shortcuts and ways to find your stuff. You can now watch H.264 video on your computer or devices like the Xbox 360.

New features include a small TV guide, a better way to move through shows, colorful labels for different shows, and easier access to online content with your TV channels. All versions of Windows 7 can support up to four TV tuners. When looking at your music or pictures, you’ll see clearer labels and better ways to sort them. There’s also a new section to quickly see media shared from other computers. The TV features now support special TV cards and favorite channel lists.

Format support

Windows 7 can now play more types of music and video files, like AVI, WAV, and AAC/ADTS. It also supports files in MP4, M4A, M4V, MP4V MOV, and 3GP formats, as well as MPEG transport stream files.

The system includes better tools to play back many popular formats, such as DivX, Xvid, and Nero Digital, along with MJPEG and DV. Windows Media Player 12 uses these tools to play these files by default. It also improves support for playing back MPEG-2 and Dolby Digital content with newer codecs.

Security

The Action Center, previously known as Windows Security Center, now handles both security and maintenance tasks. It had different names in earlier versions of the software.

Windows 7 introduced a new way to manage User Account Control, allowing users to choose from four different notification levels. A new default setting is available for this feature. There is also a geo-tracking feature, which is turned off by default. When turned on, users can only allow certain apps to track their location.

Windows 7 improved file encryption by supporting new mathematical methods for security. It can also work with older methods to keep things compatible with earlier versions.

The system now allows more applications to use protected audio features without needing special designs. It also enforces stricter rules for copying protected content.

Biometrics

Windows 7 added a new Biometric Framework to make using fingerprint scanners easier. Before, each device needed its own special software, which caused problems. Now, Windows handles the basic functions, making things more reliable.

A new control panel helps users manage their fingerprint data, troubleshoot issues, and choose what kinds of logins are allowed using biometrics. Settings can also be adjusted using Group Policy.

Networking

Windows 7 added new tools to help connect devices more easily and safely. One tool is called DirectAccess, which helps keep connections secure. Another tool, BranchCache, makes data move better over networks.

Windows 7 also introduced HomeGroup, a simple way for homes to share files. HomeGroup uses a password to let computers share files and folders without needing complicated settings.

The Windows Firewall was improved to use different safety rules for each network a computer connects to. This helps keep information safer. Windows 7 also added support for DNSSEC, which helps protect the information used to find websites on the Internet.

Management features

Windows 7 included Windows PowerShell 2.0 that you can use right away. You can also add it to older computers.

Other new tools for managing the computer are:

• AppLocker, which helps decide which programs can run on a network.
• Group Policy Preferences, which helps set rules for groups of computers.
• The Windows Automation API, which helps make tasks easier to do automatically.

Upgraded components

Windows 7 includes updated tools such as Internet Explorer 8, .NET Framework 3.5 SP1, and Internet Information Services (IIS) 7.5. Programs like Paint, Calculator, Resource Monitor, the on-screen keyboard, and WordPad have also been improved.

Paint and WordPad now have a new look, similar to Office 2007, and include extra features. WordPad can open more kinds of files. The Calculator has new ways to solve problems and a new appearance. There is also a new Sticky Notes app to help you see and organize your notes better. Resource Monitor now shows more information about memory and network use. The Magnifier tool, which helps users with vision needs, has been improved to work better across the whole screen.

Other features

Windows 7 brought several helpful updates. It made it easier to write notes and solve math problems. A new tool called Problem Steps Recorder lets users capture steps when something goes wrong.

The startup screen was changed from a blank screen to a colorful animation with four balls that twist and merge into the Windows logo. More apps could be used at once. Developers got new tools to make programs install faster. Games like Internet Spades, Backgammon, and Checkers returned. Users could turn off more parts of Windows. Windows 7 also made it easier to use virtual machines.
