operating system. In the face of every major upgrade, users will always have some concerns. Once there is any "three long and two short", it is not fun. WinXP SP2 (hereinafter referred to as SP2), Microsoft has spared no effort to promote the upgrade program, the introduction of its importance has been everywhere, but like all major system upgrades, in order to avoid unnecessary trouble, there are still some places to pay attention. The three essentials: The correct operating system serial number is familiar to all users who use Windows. Its importance to the system is like the ID card used in our lives. A correct serial number can ensure SP2 was successfully installed. In addition, is the version number of the system, you know, if you want to upgrade directly from Win98 to SP2 is impossible, because SP2 is WinXP SP2. It should be said that this time Microsoft did not do a very good job, the serial number check is still relatively loose. However, some pirates have modified a large number of system files in order to avoid the activation module, so that the SP2 installation program does not recognize that the operating system is WinXP, and the installation will of course fail (the language version may not be correct). If you are worried about whether the WinXP serial number you use is Microsoft-approved, you can go to the official Microsoft site to check it online. After opening the webpage, click "Start:Validate Now" under "1.Run the Windows Validation Assistant". At this time, you will be asked to install an ActiveX plugin. After agreeing to wait for the scan after installation, you will get the result soon. If the result is "Congratulations, it appears that your Windows product key is valid." It means that the serial number is no problem. If it is "It appears that your Windows product key is not valid.", it means that the serial number is not confirmed, so upgrade. Be careful when SP2 (some can also be upgraded successfully).
Essentials 2: Shut down all non-critical processes
Figure 2: End all non-essential processes
When installing SP2, all non-essential processes should be closed. The standard practice is: first close all applications, then use "Ctrl + Alt + Del" to bring up the task manager, go to the "Processes" tab, select each process in turn, click the "end process" button, stop all unnecessary processes (The necessary process is not finished, will give a hint).
It is not recommended to install SP2 in CleanBoot or Safe Mode, because the SP2 installer itself requires a lot of services, and these support may not exist in CleanBoot or Safe Mode. However, in normal startup mode, SP2 needs to ensure full access to all required resources, including write permissions. If you open other processes at this time, it may cause write locks on the resources. The result is not the application crash or the installation process is aborted, so all non-essential processes should be closed.
essentials III:
if disconnected from the network, said the issues highlighted in this discipline is mainly for those who have not played MS04-011 patch, so that they install SP2's long The process is not to be cried out by the sudden shock wave countdown dialog box, then those who have already played this patch may ignore this discipline. But I still have to say that this discipline should be regarded as a basic criterion.
SP2 will install a brand new network firewall for WinXP. During the installation process, the original Internet Connection Firewall (ICF) will be disabled first, and then the new service will be installed. In this process, there will inevitably be a period of security-free period, and tragedies often occur here. Therefore, it is recommended to unplug the network cable when installing SP2, and then plug it in after the end of the whole process, which is not difficult to do.
this discipline also implicitly explains the installation of SP2, it is recommended to download to the local, and then upgrade.
Eight Points for Attention
Note a: The system parameters may change
due process of installing SP2 in the registry will make a lot of changes, so the user-defined system Parameters may be replaced by default parameters. The affected applications also include firewall applications that already exist in the system, processes registered as background services, and even other common applications (such as MS Office). It may also happen that the program parameter settings are accidentally changed after the SP2 installation is completed, so that Outlook cannot send and receive E-Mail and other errors. Therefore, check the parameter settings of each program after installing SP2.
If you are installing on a new computer WinXP, you should install WinXP, then install SP2, and finally turn to install all applications, in order to avoid the situation parameter settings are changed appearance.
Note II: drivers need to be updated
SP2 WinXP change many characteristics of the hardware abstraction layer, although most of the interface can still be seamlessly connected, but for some settings, such as CD-ROM The driver is not that simple. I have received the problem of PCI device conflict after installing SP2, which makes all the boards work abnormally and makes the system restart automatically. This is a problem of related drivers. After the corresponding update, the problem is gone. Therefore, after installing SP2, go to the official site of the driver to see if there is a patch for SP2. If there is, you should immediately hit it.
three Note: The default port open longer
SP2 installed WinXP, account will Torr shaped pieces of wire glaze application from row R sulfo chessboard coat You DP /TCP protocol, It will cause a warning from the Windows Firewall, so it may be blocked, and even some programs will not work. From the user's point of view, many programs that can be executed with confidence (such as online games) are now difficult because the ports are disabled by default. Each time a connection is made to a computer with SP2 installed, a warning is raised if the user is not present. If the connection is approved within the time limit, the connection will fail, causing the application to abort unexpectedly. To solve this problem, you can refer to this issue "After installing SP2, the program can not run? "A text.
attention to four: Some system components behavior change
Windows Messenger is a component WinXP operating system, if not to own a Windows Messenger display name before, you will after you install SP2 to The user asks for one. At the same time, unsafe file transfers will be banned. Microsoft believes that a file type in an unsafe list sent by a contact that is not in the contact list is not secure and will be banned. This list of unsafe files can be found in the Microsoft Knowledge Base article (in English).
Windows Media Player 6.4 is considered an insecure component and is no longer supported. The Windows Media Player 6.4 ActiveX control embedded on the Web page will be called a Windows Media Player 9 called "shim". Control substitution. At the same time, Windows Media Player no longer automatically executes the scripts in the WMA/WMV file, but only after obtaining the user's consent.
Note 5: The deployment engine is fully updated
Figure 3: Upgraded online upgrade feature
In SP2, the default Windows Update online update engine will be replaced with the latest Microsoft Windows Update v5. Of course, you can also manually install this engine. The method is to open the link v5.Windowsupdate.microsoft.com directly.
The local deployment script engine was upgraded from Windows Installer 2.0 to Windows Installer 3.0. It supports file-level patching technology and features such as Delta compression technology, which were not available in the Windows Installer 3.0 SDK. New function. At the same time, Windows Installer no longer supports FTP and Gopher protocols, instead using the consistent WinHTTP protocol.
So, for use Windows Installer to install applications, such as MS Office, etc., should be installed after the installation of SP2 in order to obtain Windows Installer 3.0 support.
For more information about Windows Update v5, see the publication in 2004 of 17 article "Upgrade, unlimited extension."
Note Six: Check the Web content more stringent
when using IE, most pop-up windows will be blocked. So, if you're a web designer, use as little or no pop-ups as a special effect instead of layering. For untrusted sites, IE will no longer ask the user, but directly block all unsafe content such as ActiveX controls. At the same time, IE gives users the right to ban content for the entire domain, and users can choose to never download content for a domain. In this way, controls such as 3721 that use a script to force the user to install will disturb the user at most once and will be rejected forever.
Outlook Express adds some new features, such as allowing the user to open the message in plain text contains hypertext content, thereby sever inappropriate content display and possible execution. At the same time, links that are connected to the outside of the message will be difficult to open, and the default settings are never opened unless specifically approved by the user. Note
seven: optimized installation order and install content
SP2 contains a number of progressive WinXP patch, and Hotfix. Therefore, SP2 should be installed 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. Doing so is undoubtedly a waste of time and space.
Also note, SP2 includes only WinXP Home Edition, WinXP Professional Edition and Windows MediaCenter Edition common part, does not include updated versions of the three specific parts. Therefore, after installing SP2, you will still need to check for other updates to ensure that all updates for your operating system are installed. Note
eight: SP2 uninstall
uninstall SP2 is easy, but not recommended. For WinXP with SP2 installed separately, SP2 can be uninstalled. The method is also very simple, that is, the SP2 entry is deleted by "Add/Remove Programs" in the control panel, and the system will roll back to the state before the SP2 is not installed (provided that the original system was selected when SP2 was installed). status). Please note that if you have already installed other updates at this point in time, those updates cannot be undone.
If you want to uninstall SP2, must pay attention to two issues.
first: After unless absolutely necessary, such as after installing SP2, frequent system crashes, or the serious performance problem, do not unload any SP2. Especially after installing SP2, other applications are installed, and you should be more cautious when uninstalling SP2. Known errors are: After installing SP2, applications installed with Windows Installer 3.0, such as MS Office, will be damaged after the SP2 uninstallation. At this time, the application can only be uninstalled by using the Windows Installer CleanUp Utility. Can be repaired (downloaded from Microsoft officially). The application for the SP2 patch does not work properly after SP2 is uninstalled, and some can only be reinstalled. For the system, unloading and reloading is equivalent to adding two burdens, which also increases the chance of system crash and shortens the system life.
Second: Do not use the System Restore feature to "unload" SP2, this will lead to a variety of system problems. If you really need to uninstall, then uninstall from the control panel, otherwise there will be too many problems in the registry, these problems will lead to a variety of strange phenomena in the application, which makes you miserable.
for WinXP SP2 release in terms of integration, SP2 can not be uninstalled. Of course, in this case, the update is officially installed by Microsoft and directly becomes an integral part of the operating system, which will certainly not have any negative impact. This version is currently produced on the assembly line, I believe that a simplified Chinese version will be available soon.
