Automatic Updates One of the important safeguards for keeping Windows systems and software up to date. Practice has shown that turning on Windows automatic updates can avoid almost all malicious attacks that exploit system vulnerabilities. Therefore, Windows automatic update is considered by Microsoft to be one of the three important steps to ensure system security. In fact, many users do not have the function of automatically updating, causing the system to be under the risk of being attacked, or even being maliciously attacked, causing unnecessary losses. Windows XP SP2 has Windows Automatic Updates enabled by default. If the user changes the settings for automatic updates, they will be alerted or warned as shown previously. The Windows Update Service has been upgraded to version 5, and the update service is more efficient and user-friendly. In addition, automatic updates support more types of supported security patches, critical updates, cumulative update packages, service packs, and more. For slow network connection users, the BITS Background Intelligent Transfer Service greatly improves the transmission bandwidth efficiency. When using Windows Update Service, you can transfer less data and transfer data faster, reducing the pressure on updates to your corporate network. The main features are as follows: You can specify the time to download the update, for example, specify the time period when the network is idle. You can set the part that only uses part of the available network bandwidth to download only the file changes. For example, if a 1MB file only changes one byte, BITS will only transfer a few bytes instead of the entire 1MB file. Recover from a network transfer failure. During the download process, if the network fails or the connection is lost, BITS can continue to transfer from the breakpoint instead of re-downloading from scratch. Virus Protection Integration
Windows XP SP2 does not include virus protection software, but can be integrated with anti-virus software to better ensure system security. Windows XP SP2 can detect whether anti-virus software is installed. If it is not detected, it will issue a warning. If the detected anti-virus software is not updated to the latest status, it will receive a warning message. In addition, if the virus is turned off, real-time monitoring is turned off. , or the service fails to start, and a warning message will pop up. As shown below. At present, mainstream anti-virus software vendors in China have already released software products or patches compatible with Windows XP SP2. Internet Explorer
Microsoft Internet Explorer is the main Internet browser program in Windows. The user's browsing experience and security are important considerations for Windows XP SP2. The security of IE also becomes the basis of system security. Block pop-ups
Given the reality of pop-ups being abused, Windows XP SP2's pop-up blocker provides control options for users to block unwanted pop-ups. By default, most pop-ups are blocked. Once the pop-up window is blocked, a message prompt window will be displayed with a prompt in the information bar and an audible prompt. As shown below. The information prompt window explains the function of the information bar. You can select this information no longer in the new style, and the window will not pop up the next time the pop-up window is blocked. Click "Understanding Information Bar" to open the help window for IE related content. Click on the information bar to select multiple actions, as shown below.

Opening the file from the trusted site or the local intranet zone by the instantiated ActiveX control from the Web site Download and installation tips
When downloading files from IE, a prompt window will appear, as shown below. The prompt window shows the file's icon and file size. The icons below the title of the prompt window vary depending on the type and security of the downloaded file. You will also receive a security warning when installing add-ons or downloaded programs. For signed programs, there are more options to decide how to handle programs from the same issuer in the future. Add-on Management and Crash Detection
Add-ons add a variety of features to IE (such as extra toolbars, buttons, etc.), which makes browsing more interesting or efficient. Many add-ons come from the Internet, and most add-ons will prompt the authorized download and installation of the user before the download to the local computer. However, some add-ons may be downloaded without confirmation. There are also some add-ons that are installed with Windows. You can manage the add-ons in Internet Explorer and open the dialog by selecting the "Manage Add-ons" command from the "Tools" menu. As shown below. Select the "Enabled" add-on, select "Disable" from the bottom of the dialog or select the "Disabled" add-on and select "Enable" from the bottom of the dialog. The settings take effect after restarting Internet Explorer. If the add-on causes the page to not display properly or is forced to close, and a crash report pops up that detects an add-on issue, you can use that add-on only in the Add-In Manager. Or if it is an ActiveX add-on, you can try to update it to fix the problem. Outlook Express
Since in earlier versions of Windows XP, Outlook Express used the HTMLHTML control to process HTML content and automatically run the scripts contained in the Html header, posing a potential security risk. Now you can choose to read the message in plain text to reduce the risk. Some spammers include an image in their email message that references their site. Previously, when users received these messages, they automatically downloaded the image, their email address was verified to be valid, and may be added to the spam recipient address list. In Windows XP SP2, Outlook Express restricts the download of external Html content, preventing users from being spam by the spammer to verify the email address. This feature also facilitates dial-up users, eliminating the hassle of automatically dialing up when trying to read emails after downloading emails and disconnecting the network. In addition, the updated Outlook Express integrates with the AES Attachment Execution Service to prevent the saving or opening of potentially unsafe email attachments. Windows Messenger
In Windows Messenger, transferring unsafe files is automatically rejected. For a list of files that are generally considered unsafe, see http://support.microsoft.com/default.ASPx?scid=kb;zh-cn;291369 In addition, Windows Messenger also requires users to choose a different The display name of the email address.
