INTRODUCTION Windows 7 Developer Guide – Downloaded from www.WillyDev.NET 3 The Best of Windows and the Web With Windows 7, it’s easy to get connected and stay connected. Windows networking offers developers options for better caching and sharing of data to improve network performance. Network diagnostics in Windows 7 give developers relevant information for monitoring network issues. Internet Explorer™ 8 is the essential platform for building fast, rich Web experiences. Whether the goal is to connect devices, connect to a network, or connect to the Internet, Windows 7 provides an enhanced platform. Windows 7 Developer Guide – Downloaded from www.WillyDev.NET 4 Windows 7 provides a highly productive developer platform and tools that deliver on core operating system fundamentals. Windows 7 builds upon the Windows Vista platform, giving developers the power to build applications that are compatible with both platforms while limiting application compatibility issues. Windows 7 dramatically improves performance and power management so that you can create applications that optimize the mobile experience. As a result, your applications will be more visually appealing, easier to create, and support a wider range of international standards. Advances have also been made in global support, accessibility, and application deployment. Compatibility and Reliability Windows 7 is designed to run on the same hardware as Windows Vista, and to be compatible with applications and device drivers that work with Windows Vista. Windows 7 is the most reliable version of Windows yet. Designed on an improved technology foundation, Windows 7 allows users to reliably start up, shut down, or hibernate their computers without having to worry about losing valuable work. Furthermore, Windows 7 makes it easier than ever to back up and restore data to network drives or DVDs. Windows 7 also improves upon print reliability and performance. Applications To help ensure compatibility, Windows 7 has been designed in close partnership with software vendors and PC manufacturers. Early engagement has enabled Microsoft to build a comprehensive list of the most widely used applications. Automated testing cycles ensure that compatibility issues are detected and fixed early in the development cycle. Drivers The Windows Driver Kit (WDK) Version 3.0 provides the build environment, tools, documentation, and samples that developers need to create quality drivers for Windows. The WDK 3.0 supports static source code analysis, using PREfast to detect certain classes of C and C++ coding errors. PREfast includes a specialized driver component, known as PREfast for Drivers (PFD), which detects errors in kernel-mode driver code. In addition, the WDK has been enhanced by annotating all kernel header files for PFD support. New sample drivers have been added that demonstrate new technologies, and the documentation has been expanded. SOLID FOUNDATION Windows 7 Developer Guide – Downloaded from www.WillyDev.NET 5 Windows 7 supports a large variety of software and hardware products designed to integrate seamlessly with the platform. Drivers that were created for Windows Vista should not require updating to run correctly in Windows 7. Devices Windows 7 provides flexible, robust support for a wide variety of applications and devices, including music players, storage devices, mobile phones, and other types of connected devices. Automatic testing of these devices is used to ensure that compatibility issues are fixed early in the development cycle. Reliability Access Monitor Reliability Analysis Component is an in-box agent that provides detailed customer experience information on system usage and reliability. This information is exposed through a Windows Management Instrumentation (WMI) interface, making it available for consumption by Portable Readers Systems. By exposing Reliability Analysis Component through a WMI interface, developers can monitor and analyze their applications, increasing reliability and performance, Windows 7 uses the built-in Reliability Analysis Component to calculate a reliability index which provides information about your overall system usage and stability over time. Reliability Analysis Component also keeps track of any important changes to the system that are likely to have an impact on stability, such as Windows updates and application installations. You can use the Reliability Monitor snap-in to see trends in your system's reliability index correlated with these potentially destabilizing events, making it easy to trace a reliability change directly to a particular event. Management and Deployment IT professionals or developers preparing to deploy Windows 7 will have increased confidence and experience a shorter evaluation cycle due to improvements in imaging features and tools. These include support for managing applications, drivers, and operating systems in offline image files. Additionally, image creation and management will be easier and will be available to a broader range of IT organizations. Deploying Windows 7 to business PCs will also be easier and faster because of new IT migration tools and automated deployment technologies. Windows PowerShell 2.0 Windows PowerShell™ is a complete .NET managed scripting language with both an interactive command line shell and a graphical Integrated Scripting Environment (ISE). It supports branching, looping, functions, debugging, exception handling, and internationalization. PowerShell 2.0 is part of Windows 7 Developer Guide – Downloaded from www.WillyDev.NET 6 Windows 7 and delivers many enhancements and a growing set of cmdlets for Windows Diagnostics, Active Directory®, Internet Information Services (IIS) and more. The PowerShell 2.0 remoting feature now allows users to run commands on one or more remote computers from a single computer running Windows PowerShell. Developers can also host Windows PowerShell on Internet Information Services to access and manage their servers. PowerShell 2.0 supports partitioning and organizing PowerShell scripts using modules that can be distributed and deployed as self-contained, reusable units. It also includes transactions support in the PowerShell engine and APIs, which means that developers can start, commit, and rollback transactions using built-in transaction cmdlets. Further, the PowerShell engine includes eventing support for listening, forwarding, and acting on management and system events. PowerShell applications can be written to subscribe to certain events for synchronous or asynchronous processing. Windows PowerShell is a complete .NET managed scripting language with both an interactive command line shell and a graphical Integrated Scripting Environment (ISE) Windows Installer Windows Installer has been updated to increase developer efficiency by reducing the amount of custom code required to create an installation package and create true per-user software installations. Windows 7 Developer Guide – Downloaded from www.WillyDev.NET 7 Multiple Package Transaction allows developers to create a single transaction from multiple packages, using a “chainer” to dynamically include packages in the transaction. If one or more of the packages do not install as expected, simply roll back the installation. Embedded UI Handler makes custom UIs easier to integrate by embedding a custom user interface handler in the Windows Installer package. Embedded Multiple Package Chainer allows developers to enable installation events across multiple packages. For example, they can enable install-on- demand events, repair events, and uninstall events across multiple packages. New features also enable the creation of true per-user installations, including support for per-user program files and "elevate now" functionality, and provide support for offline software inventory and patch applicability checks through Deployment Image Servicing and Management. Security Windows 7 includes new and improved security features that make it easier for developers to improve, use, and manage the security of their applications. It comes with a variety of new security features that not only help protect against threats but also limit the damage that attackers can do if they gain access to a computer. Enhancements to the Windows Filtering Platform allow developers to create applications that interact with the packet processing in the networking stack of the operating system. Network data can be filtered and also modified before it reaches its destination. Also, due to changes to the Windows privilege model, system security is more manageable by both developers and their end users. New improvements make it easy to identify critical prompts to ensure that users can access the applications and features they need without compromising their systems. Windows Filtering Platform In Windows 7, the Windows Filtering Platform has been enhanced to give developers more control over firewall functionality. The level of filtering has been increased and ISVs can now plug in custom protection and detection at lower levels. In addition, firewall developers can selectively turn parts of the Windows Firewall on or off. Using Windows Filtering Platform, developers can build firewalls, intrusion detection systems, antivirus programs, network monitoring tools, and parental controls into their applications. Windows Filtering Platform integrates Windows 7 Developer Guide – Downloaded from www.WillyDev.NET 8 with and provides support for a wide variety of firewall features, including authenticated communication and dynamic firewall configuration based on applications' use of sockets API (application-based policy). Windows Filtering Platform also provides infrastructure for policy management, change notifications, network diagnostics, and stateful filtering. The initial architecture of Windows Filtering Platform in Windows Vista ® provided capabilities for IP-based traffic. Other non-IP protocols—such as such as Address Resolution Protocol (ARP) and media access control (MAC)-layer protocols for network management and authentication—also require filtering, inspection, or logging. In Windows 7, an NDIS inspection layer that supports MAC and ETHERNET filtering has been provided to satisfy this need. User Account Control User Account Control is a security component in Windows 7 that allows developers to build applications that enable users to perform common tasks as non-administrators. Developers can reduce security risks by running applications under a standard user token, reducing the risks of mistakes or attacks. User accounts that are members of the local Administrators group will run most applications as a standard user. By separating user and administrator functions while enabling productivity, User Account Control gives developers greater control over the level of access that users have over protected areas of an application. User Account Control requests credentials in a Secure Desktop mode, where the entire screen is protected to prevent spoofing of the user interface or the mouse. Performance Windows 7 maximizes hardware energy efficiency and scalability while maintaining high performance. Energy efficiency is improved through reduced background activity and new support for the trigger starting of system services. Windows 7 also offers improvements in the Windows kernel that enable applications and services to scale efficiently between platforms. Performance of many features and APIs is improved in Windows 7 versus Windows Vista. For example, driver performance on servers is optimized by new user-mode and kernel-mode topology APIs. Graphics rendering is considerably smoother and faster. Accessibility performance is also significantly faster than before. Windows 7 Developer Guide – Downloaded from www
