Solve the problems often encountered in Windows XP SP2

Summary encountered a lot of problems, I hope to help everyone

Question 1: After I installed SP2 successfully, I always found a red shield in the taskbar when I booted up. Click to enter the prompt “ virus protection is not enabled & rdquo;, I installed Norton Security SWAT 2004! What happened? But these two days mysteriously disappeared! Later I think Norton's own firewall is better, just in In the option, the firewall that comes with Windows is turned off, but there is a red shield in the taskbar. What should I do?

A: In SP2, Microsoft joined a security center. & rdquo; console, it is mainly to detect the status of virus protection, firewall, automatic update in the system. If it is not detected, a red shield will automatically pop up at boot to indicate a warning. In fact, Windows SP2 can't accurately detect most anti-virus software, even if you have it installed correctly! In fact, you just need to go to “Control Panel", click “Virus Protection” under “recommendation”, Check "Already have installed anti-virus program and monitor the status of yourself", it will not remind you when you turn it on next time. Now, major anti-virus software vendors have improved compatibility with SP2, as long as they are upgraded to the latest version. Your "mysterious disappearance" is actually the software itself is automatically upgraded and updated. In addition, the problem of the firewall can be referred to the above method of "virus protection", which is carried out in the "Firewall" tab. In addition, you can also find the Security Center Service & Security Center from the “Control Panel & Rarr; Management Tools & Rarr; Service & rdquo; window to disable it.

Question 2: I am using ADSL virtual dial-up Internet, no IP is set. After installing SP2, every time you open ADSL Modem, the system will automatically find the IP address, which will naturally fail every time, and the dialog box for renewing IP appears. And the local connection always has a yellow exclamation mark, showing "restricted or no connection", although it does not affect dialing, but it feels bad, how can I prohibit this problem?

A: This problem stems from the network card does not have A fixed IP address, in order to ensure communication, Windows automatically assigns an IP address to the network card.

Method 1: Enter the control panel, cancel “ network connection & rarr; local connection & rarr; attributes & rarquo; regular & rdquo; tab under the "notice when this connection is restricted or no connection" & rdquo; this option .

Method 2: Specify an IP address for your network card in the “Network Connection & Rarr; Local Connection & Rarr; Attribute & Rarr; TCP/IP” attribute (Note: Be sure to keep the IP address of the ADSL Modem Same network segment). It is recommended to use the second method, which can also reduce the boot time!

Question 3: I use dual system. After installing SP2, found in the dual boot menu file: boot.ini file "multi(0)disk(0)rdisk(0)partition(2)\\Windows="Microsoft Windows XP Professional" /fastdetect /NoExecute= OptIn” has more than one/NoExecute=OptIn” one, but does not affect the use of dual systems. What does this mean?

A: It is due to another important security feature in SP2 - "Data Execution Protection (referred to as: DEP)". You can find it in “Control Panel →System →Advanced →Setting →Data Execution Protection”. When you switch between these two, “/NoExecute=OptIn” will also become ““/NoExecute=Optout”. Note: This feature requires hardware support: AMD Athlon 64, AMD Opteron, Intel's Itanium and Itanium 2, and companies such as NVIDIA, VIA, and Transmeta are also expected to add the technology to their chips. It is recommended that ordinary users do not modify it, otherwise it will cause the system to run unstable. (For more information on DEP, please refer to Microsoft's KB875352 knowledge base file.)

Question 4: Due to work reasons, I often use China Merchants Bank's online banking business. Can I upgrade to SP2 and find that I can't see the verification code? What can I do?

A: In some websites that require authentication (such as online banking), most of them use the asp to dynamically generate images in Xbm format. To display the verification code. However, SP2 does not support Xbm format pictures by default, which makes it impossible to see the verification code. We can do this by modifying the registry: Click "Start”→“Run”, enter “regedit” Enter and enter the registry, navigate to: HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Internet Explorer\\Security, in In the right window, create a new dword value <;blockXbm” and set the key value to “00000000” to take effect after restart.

Question 5: When I installed SP2, I want to use Windows update to see the "Rules" in the "Rules"  V5” error message when upgrading the website "HTTP5000 error & mdash; intranet 0x8ddd0010 error" ;, can't access the site. What can I do?

A: This is caused by a conflict between the IE popup blocker and Windows update. Solution: Open IE browser, select the Tools menu → Internet Options → Privacy & Rarr; Settings, in the "Allowed Website Address" to join " http://v5.Windowsupdate.microsoft.com” (not Include double quotation marks), then click “Add”, and finally “Close& rdquo;This window will do.

Question 6: I am a maintenance person of a website, and sometimes I need to check the validity of some pop-up URLs. Since the SP2 is installed, all the pop-ups have been blocked. What can I do?

A: If you need to view the pop-ups frequently, you can disable this function: Go to the IE Tools menu → Internet Options → Privacy, cancel the checkbox in front of "Block pop-ups" and click OK to turn it off. If you occasionally allow pop-ups, you can temporarily skip this feature by holding down the Ctrl key or holding down the Ctrl key while clicking the link containing the pop-up window and clicking “Refresh”.

Question 7: After installing SP2, the Internet zone security level defaults to intermediate. When I want to lower the security level, a pop-up dialog box prompts that the security level is not allowed to be lowered. How to solve it?

A: The solution is to open Notepad, enter the following text, and save as REG registry file. Double-click to import the registry and it will take effect after restarting.

Windows Registry Editor Version 5.00

←(Note here is a blank line)

[HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\Zones\\3

"MinLevel"=dword:00010000

Question 8: I often use BT to download, but since upgrading to SP2, I found that the download speed is much slower, and when using BT download There is a problem that the webpage cannot be opened. What is the reason?

A: This is because SP2 limits the maximum number of concurrent connections to TCP. The purpose is to increase network security and prevent network crashes caused by worms such as shockwaves. . This restriction is only a limitation on the number of concurrent connection threads, and there is no limit if the connection is completed. This restriction has a certain impact on downloads such as bt, but does not affect its final download speed. If you feel that the download speed is slow, it is a problem with the built-in firewall. If you have a third-party firewall (such as Skynet) installed, you can turn it off. If you don't want to turn off your own firewall, you can solve this problem: Go to the Windows Firewall, check the UPnP “Frame” in the "Exceptions" option, and edit, in the pop-up window, “Edit Service” “Change Range&rdquo ;, then select “ any computer (including computers on the Internet) & rdquo;.

For questions about not being able to open a web page, you can download the official version of BitComet at the address below. The maximum number of simultaneous TCP connection attempts has been increased in this release, reducing the impact of the XP SP2 connection limit.

Question 9: In SP2, the function of blocking pop-ups has been provided. It feels good! Unfortunately, I like to use GreenBrowser to browse the web. Although it is based on the IE core, it does not support this new feature, but it also comes with a similar plugin. But I always feel a little regret! Excuse me, is there a way to use it?

A: Of course! The easiest way is to change the GreenBrowser.exe to iexplore.exe by going to the GreenBrowser installation directory. Although you can use this new feature, there will be some garbled characters on the bottom left, which is hard to read!! However, there is a perfect solution now:

First, please download the Maxthon Maxthon browser here. Then extract to any directory, go to this directory and find the sp2settings.reg file. Right-click and select “Edit” to open this file. Use the “Find Replace” function to replace “maxthon.exe” with “GreenBrowser.exe” and save and exit. Double-click this file to import the registry. Try it out!!

Tip: If you don't want to use this feature, please find sp2removal.exe and replace it as above. Finally, import will be able to "uninstall" this function. In addition, if you use other IE-based browsers such as MYIE, you can follow this method, and it is also effective!

Question 10: After installing SP2, I found that the system partition is a few hundred megabytes less. After inspection, I found that there is a directory in the c:\\Windows\\ directory, which is 349MB. In addition, the c:\\Windows\\ServicePackFiles folder actually has 400MB!!! What is this? What? Can it be deleted?

A: $NtServicePackUninstall$” The folder is the folder needed to uninstall SP2. After being deleted, you can't use the control panel to uninstall SP2! Of course, if you use stable, do not want to uninstall SP2, you can delete it!!

“ServicePackFiles”There is SP2 installation file in the folder. . If you delete it, you may need to insert the SP2 installation CD when you add some new features (such as adding a Bluetooth peripheral). If you have integrated SP2 into the Windows XP installation CD, you can also remove it. Of course, please choose according to your specific situation.
