Windows XP SP2 troubleshooting skills

This article focuses on some of the faults that may occur during the use of Windows XP SP2, and the author provides a solution.
1. Retrieve the missing IE image Verification Code
After SP2 is installed, most users find that the verification code image (displayed as a Red Cross) cannot be displayed when accessing some places where the verification code needs to be entered. This is a very serious BUG. Solution: run the "Regedit" command to open the Registry Editor and locate "[HKEY_LOCAL_MACHINE \ SOFTWARE
\ Microsoft \ Internet Explorer
\ Security] ", create a REG_DWORD value named" BlockXBM "on the right of the window and set it to" 0 "(hexadecimal value ).
2. Solve the Problem of slow BT download speed
After installing SP2, many friends found that if you open the BT download file, either BT obviously slows down, or when you open the web page again, the speed may be exceptionally slow, or even the problem of "cannot open the web page" may occur. This is because the number of TCP connection requests is limited to 10 by default in SP2. Currently, we can solve this problem in two ways:
Method 1: disable anti-virus software. Disabling anti-virus software can alleviate this problem to some extent, but this method is not recommended for system security.
Method 2: Modify the tcpip. sys file. We use Winhex (which is: [url] http://js-http.skycn.net: 8180/down/HA_WHex11_2SR1_ZQ.rar) [/url] to complete the modification. The specific method is as follows: tcpip under \ WINDOWS \ SYSTEM32 \ DRIVERS directory. copy the sys file to another directory, use Winhex to open the backup file, and locate lines 00000130 and 4F322 In the offset column, respectively, change the original values "6E 12 06 00" and "0A 00 00" to "62 13 06 00" and "fe ff 00" respectively ". Save the files and copy them to overwrite C: \ WINDOWS \ SYSTEM32 \ DRIVERS, C: \ WINDOWS \ SERVICEPACKFILES \ I386, and C: \ WINDOWS \ SYSTEM32 \ DLLCACHE folder with the same name. It is worth noting that the modification data of SP2 2180 is described above. For data values of other versions are different, you can refer to [url] http://www.lvllord.de/4226fix/4226fix-en-manual.htm#/url.pdf for the data of table grits in.
Tip: You can also directly use the patch prepared by a foreign expert (applicable to most popular SP2 versions. copy the sys file to a directory, download the patch (for: [url] http://www.lvllord.de/4226fix/EvID4226Patch20c.exe) [/url] And put it in tcpip. run the command in the directory where sys is located, restart the computer, and then set tcpip. copy the sys File to overwrite the preceding three folders.
3. Bring Style XP back to life
Many friends are using Style XP to beautify the system, but Style XP cannot be used after SP2 is installed. There are two solutions ,: [url] 81 EC 88 00 00 00 A1 18 "changed to" 33 F6 8B C6 C9 C2 08 00.
4. Modify the default security level of IE
Many of our friends found that after installing SP2, when we modify the Security Settings of IE below its default settings, the system will prompt "cannot modify ......" This is because SP2 imposes limits on user security levels. However, this may cause us to fail to access some sites. We can use the following method to modify its default security level: run the "Regedit" command to open the Registry Editor, go to [HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet Settings \ Zones \ 3], change "MinLevel" to "10000" (hexadecimal) on the right side of the window, so that you can set a lower security level.
5. Let Maxthon use the pop-up window control function of SP2
After SP2 is upgraded, IE adds the pop-up window interception function, which allows us to easily intercept most pop-up advertisements. Its powerful function can even block some windows that cannot be filtered by Maxthon. However, this function can only be implemented in IE. If you want to use this function in multiple page views of other IE core such as Maxthon and GreenBrower, you only need to change the file name of maxthon.exeunder the maxthoninstallation directory to iw.e.exe. It should be noted that after renaming, we need to set Maxthon as the default browser again.
6. Disable "Windows security alarm" on the system tray"
By default, Windows security alarms will pop up a prompt window when you Disable Windows Firewall, do not install firewall software, and do not enable automatic update. We can open the security center component in the control panel, click "change security centers' notification method" on the right of the window, and deselect "firewall", "automatic update", and "virus protection.
7. Two methods to uninstall SP2
You can uninstall SP2 by using either of the following methods: 1. uninstall it in the Add/delete program component on the control panel; 2. Run the "CMD" command to enter the Command Prompt window and enter the following command:
Cd % Windir % \ $ NtServicePackUninstall $ \ Spuninstspuninst.exe follow the prompts.
