Windows XP SP2 has been released for a long time, and many friends have installed it. However, during use, you have encountered one or the other problem. Here, I summarize some common problems based on my experience, I hope to help my friends!
One question: I installed after the success of SP2, always found a red shield in the taskbar at startup. Click to enter the prompt "virus protection is not enabled", I installed Norton Security SWAT 2004! what happened? But these two days have disappeared mysteriously! Later, I felt that Norton's own firewall was better. I turned off the firewall that comes with Windows in the options, but there is a red shield in the taskbar. What should I do?
A: In SP2, Microsoft added a "security center" console, it is mainly detection system virus protection, firewall, automatic update of the state. 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 enter the "Control Panel", click "Recommended" under "Virus Protection", check "I have installed anti-virus program and monitor the status of myself", will not remind you the next time you turn it on. 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. The other firewall problem can be referred to the "virus protection" method above, of course, in the "firewall" tab. Alternatively, you can find the Security Center service Security Center from the Control Panel→Administrative Tools→Services window and deactivate it.
Second question: I use ADSL virtual dial-up, not set IP. 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 the dialing, but it does not feel good, how can I prohibit this problem?
A: This question comes from the card is not a fixed IP address, in order to protect communications, Windows automatically assigns an IP address to the network card.
Method 1: Enter the control panel and cancel the option "Notify me when this connection is restricted or no connection" under the "Network Connections → Local Area Connection → Properties → General" tab.
Method 2: Specify an IP address for your network card in the "Network Connection → Local Area Connection → Properties → TCP /IP" attribute (Note: Be sure to be in the same network segment as the ADSL Modem IP address). It is recommended to use the second method, which can also reduce the boot time!

Three questions for the ADSL dial-up Modem: I am using dual system. After installing SP2, I found "multi(0)disk(0)rdisk(0)partition(2)\\Windows="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn in the dual boot menu file:boot.ini file" There is more than "/NoExecute=OptIn", but it does not affect the use of dual systems. What does this mean?
A: It is because SP2, another important safety feature - "Data Execution Protection (abbreviation: DEP)" produced. You can find it in Control Panel → System → Advanced → Settings → 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, it is said that nVIDIA, VIA, Transmeta and other companies also plan to add the
technology
to their chips. It is recommended that ordinary users do not modify it, otherwise it will cause system instability. (If you want to know more For more questions about 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. I can upgrade to SP2 and I can't see the verification code. A: What should I do?
A: In some websites that require authentication (such as online banking), most of them use the Xbm format image dynamically generated in ASP to display the verification code. But SP2 does not support it by default. Xbm format image, can not see the verification code. We can modify the registry to complete: click "Start" → "Run", enter "regedit" Enter and enter the registry, navigate to: HKEY_L OCAL_MacHINE\\SOFTWARE\\Microsoft\\Internet Explorer\\Security, create a new dWord value "blockXbm" in the right window and set the key value to "00000000", which will take effect after restarting.
Question 5: When I installed SP2 I want to use Windows update to see the "V5" upgrade website in "Legend" when I get the error message "HTTP5000 error - intranet 0x8ddd0010 error", can't access the website. What can I do?
A: This This is caused by the conflict between the IE popup blocker and Windows update. Solution: Open IE, select Tools menu→Internet Options→Privacy→Settings, and add “http in “To allow website address”: //v5.Windowsupdate.microsoft.com
” (without double quotes), then click “Add” and finally “Close” the window.
Question 6: I am a website maintenance People, sometimes need to check the validity of some pop-up URLs. Since SP2 has been installed, all pop-ups have been blocked. What can I do?
A: If you need to Look at the pop-up window, you can turn off this feature: go to the IE Tools menu → Internet Options → Privacy, uncheck the box next to “Block pop-ups”, then click OK to turn off this feature. If you occasionally allow pop-ups, you can click Hold down the Ctrl key or hold down the Ctrl key and click "Refresh" when you have a pop-up link, which temporarily skips this feature.
question seven: After the installation of SP2, Internet zone security level to medium by default. 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 then double-click Save As REG registry file into the registry, restart to take effect.
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 eight: I often use BT download, but since upgrading to SP2, we found download a lot slower, and can not open a web page be a problem when using BT download. What is the reason?
A: This is because SP2 limits the maximum number of concurrent connections TCP connections, which are designed to increase network security and prevent shock when as a kind of worm outbreaks caused by network crash. 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 do this: Go to the Windows Firewall, check the UPnP "Frame" in the "Exceptions" option, and edit, in the pop-up window "Edit Service" "Change Range", then select "any computer ( Including computers on the Internet)".
For questions open web pages, can go to the following address to download the official version of BitComet can. The maximum number of simultaneous TCP connection attempts has been increased in this release, reducing the impact of the XP SP2 connection limit.
question nine: SP2 is already provided in the shield pop-up window function, feel pretty 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 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 now a perfect solution:
First download the Maxthon Maxthon browser. Then extract to any directory, go to this directory and find the sp2settings.reg file. After selecting it, 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 now! !
Tip: If you do not want to use this feature, please find sp2removal.exe and replace it as above, and finally import can "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 ten: After I finished installing SP2, found less a few megabytes of system partition. After checking, there is a "$NtServicePackUninstall$" directory in the c:\\Windows\\ directory, which is actually 349MB! In addition, the c:\\Windows\\ServicePackFiles folder actually has 400MB! ! ! What is this? Can I delete it?
A: The "$NtServicePackUninstall$" folder is the folder needed to uninstall SP2. You can't use the Control Panel to uninstall SP2 when it's deleted! Of course, if you use stability and don't want to uninstall SP2, you can delete it! !
The "ServicePackFiles" folder exists in the SP2 installation file. 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.
