Features new to Windows 7

Windows 7 brought many exciting updates that made using computers easier and more fun. One of the biggest changes was better support for touch screens, which let people use their fingers to click and swipe instead of a mouse. This made 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 keeps the same look as 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 brought new ways to use your computer by touch. Devices that could recognize multiple touches at once could work with special programs, like a virtual piano, maps, and a version of Microsoft Paint that responds to touch.

The system also could work with sensors, like ones that detect movement, light, or location. These help adjust screen brightness based on lighting and show location information in some tools. For safety, these sensors are turned off by default and need permission to share location details.

Power management

Windows 7 has several new features to help manage power better on laptops. It can tell you when the laptop battery needs to be replaced by working with the battery’s own design.

The system also lets you change how much space is used for saving the computer’s state when it goes to sleep. It usually sets this to about three-quarters of the computer’s memory and makes the saved information smaller to fit better. There is also a new tool to check and report on how well the computer uses energy, showing details about devices and settings. Windows 7 can also turn off certain parts of USB ports to save power when they are not in use.

Graphics

Windows 7 brought several updates to its graphics features. It included Direct3D 11, which builds on earlier versions and improves how the computer shows 3D images. New tools like Direct2D and DirectWrite help make images and text look better and faster.

The way Windows handles windows on the screen, called the Desktop Window Manager, was also improved. It now works better with different types of graphics cards and uses less memory, making the computer run more smoothly. Users can also set their own screen size preferences without restarting the computer.

File system

Windows 7 brought several updates to improve how it works with different types of storage.

One big change was for solid-state drives (SSDs). These drives work differently from regular hard drives because they have no moving parts. Windows 7 was updated to better support SSDs by reducing unnecessary actions that could shorten their life. It also uses a special command called TRIM (if the SSD supports it) to help keep these drives working well.

The Enterprise and Ultimate versions of Windows 7 also allowed users to use virtual hard disks (VHD) as if they were 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 wouldn't work when using a VHD.

Windows 7 also made small improvements to how it handles removable media like USB drives and camera cards. For example, 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 designed to start up faster than earlier versions. Many computers with Windows Vista took more than 30 seconds to start, partly because they loaded extra programs that weren’t needed right away. The team working on Windows 7 focused on making the starting process quicker by improving how the computer prepares its parts to work together. They also aimed to use the computer’s processing power, storage, and memory more efficiently to help it start up faster.

Kernel and scheduling improvements

Windows 7 made some changes to how it manages tasks and memory to work better with many processors. One big change is a new way to handle tasks in user-mode, which helps programs that need many threads run faster without needing the kernel to manage every switch between tasks. This also allows programs more control over how their tasks are handled.

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, reducing delays and improving performance. It also introduced "timer coalescing," which helps modern processors save power by grouping tasks together so the CPU doesn’t have to wake up as often.

Multimedia

Windows Media Center

Windows Media Center in Windows 7 kept many of its looks but added some handy shortcuts and ways to look through your stuff. You can now watch H.264 video on your computer or through devices like the Xbox 360.

New features include a small TV guide, a better slider for moving through shows, colorful labels for different kinds of shows, and easier access to online content alongside your regular TV channels. All versions of Windows 7 can handle 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 include support for 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 decode and 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 brought several new networking tools to make connecting devices easier and safer. One of these tools is called DirectAccess, which uses special technology to keep connections secure. There is also BranchCache, designed to improve how data moves over networks.

Windows 7 introduced a new way for homes to share files called HomeGroup. This system uses a password to let computers share files and folders easily. It works well for people who want to share things without worrying about complicated settings.

The Windows Firewall was also improved. It can now use different safety rules for each network a computer connects to, which helps keep information safer when using multiple networks at once. Additionally, Windows 7 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 ready to use, which could also be added to older computers.

Other new tools for managing the computer were:

• AppLocker, which helps control which programs can run on a network.
• Group Policy Preferences, useful for setting rules on groups of computers.
• The Windows Automation API, which makes tasks easier to automate.

Upgraded components

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

Paint and WordPad now have a new design similar to Office 2007, with extra features. WordPad can handle more types of files. The Calculator has new ways to solve problems and looks different from older versions. There is also a new Sticky Notes app that makes it easier to see and organize your notes. Resource Monitor now shows more details about how memory and network are being used. The Magnifier tool for users with vision needs has been improved to work better on the whole screen.

Other features

Windows 7 brought several helpful updates. It improved how handwritten notes and math problems are recognized, making it easier to correct mistakes with new gestures and adding a special panel for writing math. A new tool called Problem Steps Recorder lets users capture steps when something goes wrong, helping others understand the issue.

The startup screen was changed from a blank screen in Windows Vista to a colorful animation with four balls that twist and merge into the Windows logo, but this only works on screens with enough size and resolution. More apps could be used at once compared to older versions. Developers got new tools to make programs install faster and work better with different languages. Games like Internet Spades, Backgammon, and Checkers returned after being removed in Windows Vista. Users could turn off more parts of Windows, like the handwriting recognition or Windows Media Player. Windows 7 also made it easier to use virtual machines, allowing older Windows XP programs to run alongside Windows 7 apps.
