How Windows system security settings

1. Upgrade to new windows

For users who use Windows XP, upgrading to the Windows 7 operating system can improve security, and Windows 7 has a lot of security that Windows XP does not have to do to keep the operating system running safely.

　2. Update operating system Patches

The importance of installing patches on the system is self-evident, Windows Update has the ability to detect updates and install updates, and we simply set this feature to automatically check for updates, Windows Update can automatically download the system's known vulnerabilities patch and install it. The system will be downloaded in the background, after the completion of the notification you download completed and asked whether to start installation, it is very convenient to use. After you have installed all the patches, you can start to make some other adjustment settings below.

3. Be good at controlling UAC function, improve safety precaution level

The UAC feature is not a new feature of the win 7 system, but compared to the UAC features under Vista and win 2008, the user Account Control function in Win 7 has improved significantly, and the distinction between illegal operations and legitimate operations is much more intelligent, And we can according to the actual security needs to control the UAC security level freely, strives for the operation efficiency and the security performance two not to be mistaken. In order to improve the level of security, the Win 7 system specifically provides users with the UAC function control scroll bar, the user simply drag the mouse, can be operating efficiency and system security to find a balance between. To keep the win 7 system as stable as possible, we should try to adjust the UAC security level to "always notify," and with this setting, the Win 7 system pops up with a much smaller security hint than the Vista system. When you adjust the UAC security level, we can click the "Start", "Control Panel" command on the Win 7 system desktop, click the "User account and home security", "User account" icon option in the Pop-up System Control Panel window, and click on the user Account Control list interface. Change the user Account Control Settings button to open the Settings dialog shown in Figure 3; Check that the control button for the UAC function is at the "Always notify" position, and if it is not in this position, we must move the move button to that position in time, and then click OK to save the setup operation so that the security guard level of the win 7 system will be significantly improved. Then the security threat to the system will naturally decline.

　　4. Use BitLocker feature to encrypt disk privacy information

Second, select the target partition that requires privacy protection, click the Enable BitLocker link on the right side of the partition, open the BitLocker Drive Encryption wizard setting interface as shown in Figure 1, select the "Unlock Drive with password" option, and then enter the appropriate unlock password; Then click the Next button, when the wizard screen asks us how to store the recovery key, we can save it as a text file as needed or print it directly, and then click the "Start Encryption" button, so that the target partition is encrypted successfully, and you must rely on the legal key to access the data content in the future. If the key content is not remembered, then no one can peek at the privacy information.

　　5. Firewall and antivirus software

Regardless of how the computer is set up, firewalls are necessary as long as they are connected to the Internet. Firewalls can completely protect the user's system, blocking the harmful things on the network outside the door. The recommended firewall is Windows's own firewall software. The system requirements are not high, not so many fancy functions, but the most basic protection can be competent. Open Control Panel-Network and Internet connections, double-click Network connection to open the Properties dialog box, under the Advanced tab, select the Internet Connection Firewall on my computer, and then click Settings for further configuration.

Antivirus software can use Microsoft's MSE (Microsoft Security essential) software to protect against viruses, spyware, and other malware intrusion. This antivirus software is free, because it was developed by Microsoft itself, so the combination of the operating system is very good, not so many fancy features, efficient and reliable.

　　6. Data backup

As the saying goes, "while, outsmart", many times almost impossible, even if we have a very perfect security settings, but encountered a number of sudden virus coming, many security measures may still be fragile. In order to avoid catastrophic damage caused by sudden virus, we only have to backup the important data in time, when we encounter system crash, we can resolve the security threat by simple data recovery operation. The Win 7 system provides users with powerful data backup and restore capabilities, we can do the following to backup the important data: first, open the win 7 system "Start" menu, select the "Control Panel" command, in the Pop-up System Control Panel window, click "System and Security", "Backup and restore "Feature icon, open the Backup and Restore Management window for the corresponding system, then continue to click the Set Backup button, open the Settings dialog box, select the partition option for the important data information, and click the Next button, and then the wizard screen prompts you to ask us what data to back up. We can choose the target backup content according to the actual need, and finally click the "Save settings and Run Backup" button, so that the target data content can be backed up successfully. Once the win 7 system is paralyzed and not functioning properly, we do not have to worry about the security of important data, simply reinstall the operating system, and then perform the System Restore function to restore the important data of good backup to success.

　7. Controlling User group permissions

If your computer often installs software, you should create a new user in the system, set it as the user group, and then log on to the system using the user group to run the software in the sandbox. In addition, the Guest account is stopped in user management and is not allowed to log in to the system at any time.

　　8. Summary

After the above settings, the computer system security should be improved a lot, but need to pay attention to, regardless of the system and software to do how to protect, the correct use habits is the most important, so from now on to develop a good habit of use, otherwise in how to protect is in vain.
