Three major essentials and eight notes for installing XP SP2 _windowsxp

The importance of operating systems is needless to say, in the face of every major upgrade, users will always have some worry, once there is any "happens" is not fun. WinXP SP2 (hereinafter referred to as SP2), an upgrade that Microsoft has spared no effort to promote, is an introduction to the importance of it, but like all major upgrades to the system, there are a few areas to look out for in order to avoid unnecessary problems.

　　 three major Essentials

　　 A: The correct operating system sequence number

The serial number is more familiar to all users who use Windows, and it's important to the system like the ID card used in our lives, and a correct serial number will ensure that SP2 is installed successfully. In addition, is the system version number, you know, if you want to upgrade from the Win98 directly to SP2 is impossible, because the SP2 here is WinXP SP2. It should be said that this time Microsoft did not do things very absolutely, the serial number of the inspection is relatively loose. But some piracy in order to escape the activation module, modified a large number of system files, so that SP2 installation program can not recognize the operating system is WinXP, installation of course will not be successful (may be the language version of the wrong prompts). If you are a bit worried about whether your WinXP serial number is approved by Microsoft, go to the Microsoft Official site and check it online. When you open the Web page, click "Start:validate Now" under "1.Run Windows Validation Assistant", and then you will be asked to install an ActiveX plugin, agree to wait for the scan after installation, will soon get results. If the result is ' congratulations,it appears that your the Windows product key is valid. "Means there is no problem with the serial number, if it appears that your the Windows product key is not valid. "means that the serial number is not confirmed, so be careful when upgrading SP2 (some can also be upgraded successfully).

　　Essentials Two: Close all non-critical processes

Figure 2: End all non-essential processes

When installing SP2, you should close all non-essential processes. The standard practice is to close all applications first, then use "Ctrl + Alt+del" to bring up Task Manager, go to the "Process" tab, select each process in turn, click the "End Process" button to stop all non-essential processes (the necessary process is not finished, will give a hint).

Installing SP2 in Cleanboot or Safe mode is not recommended because the SP2 installer itself requires a lot of service support that does not necessarily exist in either cleanboot or Safe mode. In normal boot mode, however, SP2 needs to be guaranteed full access to all required resources, including write permissions. If you turn on other processes at this time, it may cause a write lock on the resource, and the consequence is not that the application crashes or the installation process is aborted, so you should close all non-essential processes.

　　 Essentials Three: Disconnect from the network

If you say, the emphasis of this discipline is primarily on users who have not played ms04-011 patches, so that they do not have to be made to cry in the long process of installing SP2, and those who have already played the patch may disregard this discipline. But I would like to say that this discipline should be seen as a basic rule.

SP2 installs a new network firewall for WinXP, which disables the original Internet Connection Firewall (ICF) and installs the new service during the installation process. In this process, there will inevitably be a period of time of the security blind area (Security-free Period), tragedy often occurs in this. Therefore, it is recommended that the installation of SP2, the network cable unplug, and so on after the end of the whole process plug, it is not difficult to do.

This discipline also implies that when installing SP2, it is recommended that you download it locally before you upgrade it.

　　 Eight items of attention

　　 Note One: System parameters may change

Because of the large changes made to the registry during the installation of SP2, user-defined system parameters may be replaced by default parameters. Affected applications also include firewall applications that already exist in the system, processes registered as background services, and even other ordinary applications such as Ms Office. It is also possible that the program parameter settings were accidentally changed after the SP2 installation, resulting in errors such as Outlook not being able to send and receive e-mails correctly. Therefore, after installing SP2, you should check the parameter settings of each program.

If you want to install WinXP on a new computer, you should install WinXP, then install SP2, and then install all the applications in turn to avoid any changes to the parameter settings.

　　 Note Two: Drivers need to be updated

SP2 changes many of the features of the hardware abstraction layer in WinXP, although most interfaces can still be seamlessly connected, but for some settings, such as the CD-ROM driver is not as easy. The author has received the installation of SP2, PCI device conflicts so that all the work of the Board to automatically restart the system frequently, this is the problem of the relevant driver, the corresponding update after the problem is not. So, after installing SP2, go to the official site of the driver to see if there is any patch for SP2, if there is, should immediately hit.

　　 Note Three: The port is no longer opened by default

Install the SP2 WinXP, will torr the account  form from the wire Songhu R sulfonic Line  the 肬 the application of the Protocol, will raise the Windows Firewall warning, so it is possible to be blocked, even cause some programs can not run. From a user's perspective, many of the programs that were previously safe to perform, such as online games, are now difficult because the ports are blocked by default, and each time a connection is made to a computer that has SP2 installed, a warning is raised that the connection fails if the user does not approve the connection within the time limit, Thus causing the application to abort unexpectedly. To solve this problem, you can see that the program does not run after installing SP2 in this issue. "article.

　　 Note Four: Some system components behave differently

Windows Messenger is a part of the WinXP operating system, and if you have not previously given your Windows Messenger a display name, the system will ask the user for one after installing SP2. At the same time, unsafe file transfers will be prohibited. Microsoft believes that a file type in an unsafe list sent by a contact who is not in the contact list is unsafe and will be banned. This unsafe file list can be found in the Microsoft Knowledge Base article (English).

Windows Media Player 6.4 is considered an unsafe part and is no longer supported, and the ActiveX controls embedded on the Web page for Windows Media Player 6.4 will be called "shim" by Windows Media Player 9 control override. At the same time, Windows Media player no longer automatically executes scripts in the wma/wmv file, but does so with the consent of the user.

　　 Note Five: The deployment engine is fully updated

Figure 3: Upgraded online upgrade feature

In SP2, the default Windows update online update engine is replaced with the latest Microsoft Windows update v5. Of course, you can also manually install the engine. The method is to open the link v5.windowsupdate.microsoft.com directly.

The local deployment scripting engine is upgraded from Windows Installer 2.0 to Windows Installer 3.0, which supports file-level patches and previously-not-available features such as delta compression, in the Windows Installer 3.0 SDK , adding 21 new functions. At the same time, Windows installer no longer supports the FTP and gopher protocols and instead uses a consistent WinHTTP protocol.

Therefore, applications that are installed using Windows Installer, such as MS Office, should be installed after installing SP2 to obtain support for Windows Installer 3.0.

For a detailed introduction to Windows Update V5, see our 17th issue of "Upgrades, Infinity," 2004.

　　 Note Six: Network content checking is more stringent

When using IE, most pop-up windows will be blocked. So, if you're a web designer, use a layered technique with as little or no pop-up windows as a special effect. For untrusted sites, IE will not ask users, but directly screen all ActiveX control and other unsafe content. At the same time, IE gives users the right to prohibit the entire domain content, users can choose to never download the content of a domain. In this way, a control such as 3721 that uses a script to force a user to install can disturb the user at most once and will be rejected forever.

Outlook Express has added new features, such as allowing users to open messages with hypertext content in plain text, and thus sever the possibility of displaying and executing objectionable content. Also, links to the outside of a message will be difficult to open, and the default setting is never open unless the user specifically approves it.

　 Note Seven: Optimize installation sequence and installation content

SP2 contains a large number of WinXP progressive patches, as well as hotfix. Therefore, you should install SP2 first, and then use Windows Update to update other content online, such as driver updates. Although SP2 will check the file version when it is updated and only replace the part that needs to be updated, the time to download SP2 is exactly the same. To do so is undoubtedly a waste of time and space.

Also note that SP2 includes only parts of WinXP home Edition, WinXP Professional Edition, and Windows MediaCenter Edition, and does not include updates that are specific to these three versions. Therefore, after you install SP2, you still need to check for additional updates to ensure that all updates to your operating system are installed.

　　 Note Eight: SP2 uninstall

Uninstalling SP2 is easy, but not recommended. WINXP,SP2 can be uninstalled for SP2 installed separately. The method is also simple to remove the SP2 entry through Add/Remove Programs in Control Panel, and the system rolls back to the point in time before the SP2 was installed (provided that the original system state was selected when the SP2 was installed). Please note that if you have installed other updates at this point in time, then those updates cannot be revoked together.

If you want to uninstall SP2, you must pay attention to two problems.

First: Unless absolutely necessary, such as after the installation of SP2, the system frequently freezes, or the performance of serious problems, do not arbitrarily uninstall SP2. Especially after installing the SP2 and installing other applications, uninstalling SP2 should be more cautious. A known error is that, after installing SP2, applications installed with Windows Installer 3.0, such as MS Office, will have a damaged installation package after SP2 Uninstall, only by using Windows Installer CleanUp Utility The application unload load to repair (from Microsoft official download). The application for the SP2 patch is not functioning properly after SP2 is unloaded, and some can only be reload. For the system, unload and reload, equal to add two times burden, also increase the probability of system crash, shorten the system life.

Second: Do not use the System Restore function to "uninstall" SP2, this will cause a variety of system problems. If you really need to uninstall, then uninstall from the Control Panel, otherwise the registry will leave too many problems, these problems will cause the application of a variety of strange phenomena, make you miserable.

SP2 is not uninstalled for WinXP distributions of integrated SP2. Of course, in this case, the update by the Microsoft Official installation, directly become an integral part of the operating system, it will certainly not bring any negative impact. This version is now on the production line, I believe that soon there will be Simplified Chinese version published.
