What is Windows Longhorn?

In general, longhorn is the software development code of Microsoft's next-generation technology and platform. This generation of software will include new versions of Windows, Windows Server,. NET and Microsoft Office software. Windows "Longhorn" is the next generation of major Windows desktop operating systems. It is like windiws XP, but it includes many new features, such as a task-based (or smart) user interface, A Scalable and docked start panel and a file system called winfs based on SQL Server 2003. Windows Longhorn, like Windows XP, will also release the home, professional, tablet PC, Media Center, 64-bit, and other versions, however, how to determine the names of these versions is still unclear.

What new functions will windows Longhorn provide?

1. Windows Longhorn will advocate the task-based interface, which will far surpass the interface seen in Windows XP. The new user interface code name aero is a new API Based on. NET, which is called aveon.

2. the Start menu and taskbar of Windows Longhorn will be replaced by a new sidebar component, which can choose whether to dock to the desktop side based on your preferences. Sidebar is XML-based. It can link local resources or remote resources.

3. Windows Longhorn will require computers to install video hardware with 3D effects to display many special effects to make the screen more vivid. However, this does not mean that the basic windows and mouse interfaces will be replaced, but will make them look more beautiful.

4. Windows Longhorn will selectively adopt the Palladium Security Technology jointly developed by Microsoft, Intel, and AMD.

5. Windows Longhorn will adopt a database-like file system called Windows future storage (winfs). It is based on SQL server2003 technology (the code name is Yukon ). This file system extracts physical file locations and allows users to perform complex data retrieval and sorting, which is impossible today. For example, files such as emails, contacts, Word documents, and music files are completely separated. This is not the case in Windows longhorn. Winfs is not a new file system, but an extension of nfts, which still requires nfts. Microsoft is trying to make it easier for us to find the data we need in the growing hardware devices. By adding the relational database function to the file system, you can retrieve data and documents more quickly. As a Microsoft executive said, "Why do we only need a few seconds to find what we want on the Internet, but does it take more time on our own machines? ". In addition to adopting winfs technology, Microsoft also adds a new file system concept: Library, which organizes data like a collection regardless of the actual physical storage location in their systems. For example, the photo and movie library will collect links to all the electronic photos and digital images in the system.

6. Windows Longhorn will contain many anti-virus (AV) APIs, which will help developers more easily inherit their software into basic operating systems. Microsoft will also provide Longhorn users with automatic anti-virus updates to ensure that their systems maintain the latest anti-virus functions.

7. Windows Longhorn will include an integrated recordable DVD feature that recognizes any recordable DVD format. Digital media enthusiasts can directly copy a record-ready DVD from a camera instead of a hard disk.

8. Windows Longhorn will include a more advanced error reporting tool, error reporting tool (ERT), which allows users to report bugs to Microsoft and automatically fix these bugs.

9. Windows Longhorn uses a new installation mechanism that will install Windows Longhorn within 20 minutes.

10. Windows Longhorn will contain many new APIs to provide access to new functions of the system.

11. The programming mechanism of Windows Longhorn will be greatly changed. The web and windows programming models will be unified to provide both wired and offline user experience. In the Longhorn generation technology, Microsoft has completely moved to the. Net-based manageable code environment. The Longhorn generator will be clearly separated from the previous Win32 API. That is to say, Win32 will be maintained and all development is in manageable. Net API. An API that has been used as aveon forms the basic element of the desktop compositing engine (DCE). DCE replaces the previous GDI and GDI +. Another aero API provides APIs for the new user interface. All these new APIs will adopt the XML Application Markup Language (XAML), which provides developers with more convenient access capabilities than before. This idea greatly reduces the number of APIs and makes APIs more standardized. At present, there are more than 76000 wi n32 APIs and numerous packages. In Longhorn, Microsoft wants to reduce these APIs to 8000 to 10000. Another important change involves hardware drivers. In the past, Microsoft allowed consumers to use non-Signed drivers to achieve compatibility requirements, but this often caused stability problems. In Longhorn, you can only use signed drivers.

Developers are concerned about the release of Visual Studio. NET "Whidbey". Whidbey is an IDE programming environment for Windows Longhorn and is currently in beta version. Whidbey includes the visual designer of XAML. Microsoft will provide developers with the first public release of Longhorn software developer kit (SDK) at the PDC Conference in Los Angeles in October 23. Longhorn software developer kit contains the UI components and actions that developers can access.
