In SP2, if you use FlashGet to download some web pages from the Internet, and later offline in FlashGet, double-click these pages, you will It is found that IE does not display the content of the webpage normally, but opens the webpage in plain text to display the HTML code of the webpage. Another phenomenon is that when you open an mp3 media file in http in IE, the mp3 file is also displayed in plain text. This type of problem is caused by a mismatch between the file's extension and content; or the content type reported by the server does not match the file's extension. For example, a file is in the PHP content format on the server side, but after downloading to the hard disk, you change the file extension to .HTML, which will cause such problems.

SP2 In order to enhance the security of IE, MIME Handling Enforcement is enabled. In order to solve the above problems, we can first disable the security feature of IE by modifying the registry:

Click " Start "/Run, enter Regedit in the Run box, open the registry, find the HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_MIME_SNIFFIN item, click iexplore.exe (REG_DWORD type) in the right window, and set its value Set to 0.

For security reasons, SP2 stipulates that if an object contains an invalid signature, Internet Explorer will disable its installation by default. By default, even an administrator cannot download and install such invalid signed objects through Internet Explorer.

After installing SP2, if you need to download and install such invalid signature objects when browsing the page, you can use the following method: In IE, click the menu "Tools" /Internet Options, click Open the "Advanced" tab; check the "Allow running or installing software, even if the signature is invalid" option; finally confirm the exit.

After Windows XP SP2 starts, sometimes a shield icon is displayed in the tray area of ​​the taskbar, sometimes it does not appear. The icon is sometimes displayed in green. Red, or yellow.

If the SP2 Security Center is working properly, it will not display an icon in the taskbar tray area. If the security center is working properly, you can manually open the security center and a green icon will appear in the task tray area. Green indicates that the system is safe.

If a red icon appears, the current system does not have a firewall or automatic update enabled, or the virus protection software is not updated, or the virus definition library has expired. If a yellow icon appears, the system is potentially dangerous. You should open the Security Center in time to adjust the security settings to enhance the security of the system.

IX. Security Center Warning Virus Monitoring/Anti-Virus Status is Unknown

The Security Center (WSC) reports an unknown status, indicating that WSC cannot determine the virus characteristics of the virus monitoring software. The code library file, whether there has been an update recently, or whether the local library file has been updated. Because of the anti-virus software, the latest virus can be discovered and cleared after updating the latest virus signature database, so the security center should warn the user.

To do this, you should contact the anti-virus software manufacturer to confirm whether the software has an upgrade package, so that SP2 can detect its virus signature update online; if there is an upgrade package, purchase anti-virus software and update the virus. The signature database; otherwise, the security center is configured and the user manually monitors its status.

On some websites (such as China Merchants Bank website), when you register or log in, you need to enter the verification code, most of the verification. The image format of the code is .Xbm. Many Unix host websites use the Xbm format image (extension .Xbm) when designing the verification code. However, after installing SP2, the verification code on the login page cannot be displayed. , so that you can not log in or register. The reason for this phenomenon is that SP2 removes the support for the image/x-xbitmap image format by default, so the Xbm format captcha image cannot be displayed in IE.

To solve this problem, you can click "Start" /Run, type Regedit.exe in the input box, press Enter, open the Registry Editor, and then locate HKEY_LOCAL_MACHINE\\SOFTWARE in the tree on the left. \\Microsoft\\Internet Explorer\\Security, create a new DWORD button named "BlockXMB" in the right panel, set the key value to "0", and finally restart IE to solve the problem.

The second method: open Notepad, edit the following text file,

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Internet Explorer\\Security]

"BlockXBM"=dword:00000000

After saving the file as a registry file with the extension reg, double-click the file and import it into SP2.
