Windows XP is a product based on Windows2000 code, and it has a new user graphical interface (Luna), including some minor modifications, some of which seem to be inspired by Linux desktopenvironmen, such as KDE: the login interface with user graphics is an example. In addition, Windows XP introduces a "people-based" user interface, which enables the toolbar to access the specific details of tasks. It contains the simplified user security function of Windows 2000 and integrates a firewall to ensure the security problems that have plagued Microsoft for a long time. In 200 1 10, Jim Allchin, vice president of Microsoft, first showed Windows XP. Microsoft originally released two versions: the professional version and the home version. In 2002, Microsoft encountered an antitrust lawsuit from the US Department of Justice, and launched the Windows XP SP 1 patch package, allowing consumers and computer manufacturers to delete some so-called "middleware" technologies integrated in XP. In 2003, the earliest pirated XP appeared in China, that is, JUJUMAO version, which was downloaded for a fee and the installed capacity was not large. At the same time, the website of Tomato Garden was established. In 2004, Microsoft spent $300 million to support the release of XP SP2, which was a major reform of XP security architecture, adding new technologies in network protection, secure email processing, web browsing and PC maintenance. In 2005, Microsoft released two series of 64-bit XP clients and servers to support the 64-bit desktop processors of Intel and AMD. AMD was greatly dissatisfied with the delay because it had to wait for Intel's 64-bit processor. In 2006, Apple introduced the Intel chip Mac computer and opened Windows XP to users. In 2007, Windows Vista was released in high profile at the beginning of the year, adopting a brand-new graphical user interface. However, software and hardware manufacturers failed to launch Vista-supporting products in time, and negative news spread all over the sky, which also seriously affected sales. In 2008, XP SP3 patch package was launched; The market share of Windows XP in China is 75%, but the piracy rate is as high as 82%. Since the "Tomato Garden" incident, Microsoft has "closed the net" on pirated software in China. In 2009, the Windows 7 operating system was officially launched. Although Microsoft has extended the life of XP again and again, it still can't change a large number of users to use Windows 7, and Windows XP system began to be completely eliminated. Windows xp classic desktop 20 14, Windows XP operating system, terminate mainstream technical support and extend technical support.

Server version -Windows Server 2008 R2 version

Windows 7 also released the server version-Windows Server 2008 R2. Compared with Windows Server Windows Server 2008R22008 released on June 5438+ 10, 2008, the application of Windows Server 2008R2in virtualization, system management flexibility, network access mode, information security and other fields is constantly improving, and many of its functions need to be matched with Windows 7. The appearance of Windows Server 2008 R2 is not only to expand the applicability of Server 2008, but also to accelerate the popularization of Windows 7 in the enterprise environment through these mechanisms. Important new features of Windows Server 2008 R2 include: Hyper-V adds dynamic migration function as an improvement on the quick migration function in the initial version; Hyper-V will calculate the migration time in milliseconds. Compared with other hypervisors of ESX or VMware, this is the advantage of Hyper-V function. And strengthen PowerShell's management instructions for each server role. Other features include: feature1:Hyper-V2.0-the function and usability of virtualization are more perfect. Hyper-V2.0 supports real-time migration and can support more Linux operating systems installed on virtual machines. Half a year after the launch of Windows Server 2008, Microsoft launched the virtualization platform Hyper-V 1.0 based on Windows Server 2008. Although this version has the basic virtualization function, it is much weaker than other virtualization platforms, such as the lack of dynamic migration function, so it is impossible to migrate the virtual host (VM) to other physical servers without stopping the VM. Windows Server 2008 R2 Hyper-V 2.0 supports this function, which makes the usability of the virtualization platform a big step forward. New features of Hyper-V 2.0 ● Support dynamic migration ● Dynamically adjust virtual disk capacity ● Have the function of dynamically configuring VM memory ● Boot virtual image file on physical host ● Add Red Hat Linux to the operating system supported by VM ● Host. Support up to 32 processor logic cores ● Improve VM computing efficiency Features 2: Active directory management center, offline domain joining, AD resource recycling bucket -AD enhanced management interface and flexible deployment of active directory (AD) have always played an important role in Windows Server operating system, but in Windows Server 2008 R2, many functions have been enhanced. For example, it has a new advertising management interface, which can be operated with PowerShell instructions. You can also let the computer join the domain offline, and there is an advertising resource recycling station to increase the flexibility of adding and deleting advertising members. . Function 3: Windows PowerShell 2.0 and server core-server core mode support. NET, and R2 improves the shortcoming that the server core can't be used because it doesn't support PowerShell. NET framework. Now PowerShell can be used in the server core with command operation as its main appeal, making the operation of server management more efficient. Function 4: Remote Desktop Services-Enhance desktop and application virtualization. In the new version of RDS, a new Remote Desktop Connection Broker (RDCB) has been added. This function can integrate all RDS application servers, including physical hosts or virtual machines. Function 5: Direct Access-Provide a more convenient and safer remote online channel. DirectAccess makes the establishment of VPN tunnel easier, integrates various authentication mechanisms and NAP, and helps to improve the security in the online process. Feature 6: Branch Cache-a new method to speed up file access between branches. By using the file cache, you can access the previously downloaded files nearby, which not only can get the shared data faster, but also can reduce the waste of external connection bandwidth. Function 7: URL-based QoS-enterprises can further control the access bandwidth of web pages. Enterprises can define the priority of all personal computers connecting to specific websites, and speed up the access to important web pages. Function 8:BitLocker to Go- supports encryption of removable storage devices. The special feature of this step is that it can integrate smart cards to verify the authenticity of users' identities and make the control of storage devices more secure. Feature 9: AppLocker-AppLocker, a personal application with higher control, can be said to be an enhanced version of the software restriction principle. In addition to all the old functions, the most important thing is that enterprises can effectively prohibit or allow the execution of applications through publisher information that cannot be modified at will. At the same time, it improves its own safety performance. Microsoft said that starting from Windows Server 2008 R2, Windows Server will no longer launch a 32-bit system version.
