Win XP SP2 configuration and troubleshooting techniques revealed

This article mainly talks about some of the problems that Windows XP SP2 may encounter during use, and I have given a solution. 1. Retrieve lost IE image verification code

After installing SP2, most users find that they cannot display the verification code picture (shown as a red cross) when accessing some verification codes. This is a very serious bug. The solution is: run the "Regedit" command to open the registry editor, then navigate to "[HKEY_LOCAL_MacHINE\\SOFTWARE\\Microsoft\\Internet Explorer\\Security]", and create a new REG_DWord value named "BlockXBM" on the right side of the window, and set its value. Set to "0" (hexadecimal value).

2. Solve the problem of slow download speed of BT

Many friends found after installing SP2: If you open BT download file, either BT is obviously slower, or the speed is very slow when you open the webpage again. There is even a problem with "Unable to open webpage". This is because the SP2 default setting limits the number of TCP simultaneous connection requests to less than 10. Currently, we can solve this problem in two ways:

Method 1: Turn off the anti-virus software. Turning off anti-virus software can alleviate this problem to some extent, but for system security, I don't recommend this method.

Method 2: Modify the tcpip.sys file. We use Winhex (the download address is: http://JS-http.skycn.Net: 8180/down/HA_WHex11_2SR1_ZQ.rar) to complete the modification work, the specific method is as follows: First, the C:\\WINDOWS\\SYSTEM32\\ DRIVERS directory Copy the tcpip.sys file to another directory, open the backup file with Winhex, and locate the "00000130" and "4F322" lines in the offset column, and set the original values ​​"6E 12 06 00" and "0A 00 00 00". Change to "62 13 06 00" and "FE FF FF 00" respectively. After saving, copy the files in the safe mode to overwrite the files with the same name under the C:\\WINDOWS\\SYSTEM32\\DRIVERS, C:\\WINDOWS\\ SERVICEPACKFILES\\I386, C:\\Windows\\SYSTEM32\\DLLCACHE folder. It is worth noting that the above is the modified data of SP2 2180 version. For other versions, the modified data values ​​are different. You can refer to http://www.lvllord.de/4226fix/4226fix- en-manual.htm The data provided in the form.

Tip: You can also directly use a patch made by a foreign master (applicable to most popular SP2 versions), first copy the tcpip.sys file to a directory, download the patch (download address: http After ://www.lvllord.de/4226fix/EvID4226Patch20c.exe), put it in the directory where tcpip.sys is located and run it. After restarting, restart the computer. Finally, copy the tcpip.sys file to the above three folders. .

3. Let Style XP come back to life

Many friends are using Style XP to beautify the system, but after installing SP2, Style XP can not be used. There are two solutions, we can download the latest version of Style XP, download address: http://www.tgtsoft.com/download.PHP, you can also use the method of modifying uxtheme.dll: %systemroot%\\system32 Copy a copy of uxtheme.dll, open the copy with UltraEdit, and change the value of the "0001BB8C" line of the Offset column from the original "81 EC 88 00 00 00 A1 18" to "33 F6 8B C6 C9 C2 08 00" Just fine.
